Bubble Writing with Happi Crafts’ Resin Sprinkle Letters

Practice letter writing with bubbles and sprinkles! This fun activity not only works out little hands by engaging their fine-motor skills, but it also helps with coordination AND encourages ingenuity as use they everyday items in new and interesting ways. This project was inspired by the amazing blog Teach Beside Me and utilizes the wildly popular resin sprinkle letters from Happi Crafts that range from $7 to $80 with lots of design options!

Recommended age is 4+ because it requires a good amount of coordination to pinch and release the balloon to write properly.

Materials

  • Large bowl, plastic bin, or casserole dish
  • Dish Soap
  • Water
  • Balloon
  • Pen or marker with no ink left
  • Duct tape
  • Waterproof letter prompts (can also use any type of letter prompt here, just lay them next to the bowl instead of submerging them if they’re not waterproof.)

Method

  1. Remove the ink chamber in the pen or marker till just the casing is left. Wash all the residual ink away, if any. Leave the casing open at both ends.
  2. Secure the balloon onto the non-writing end of the casing with duct tape.
  3. Add a squirt of dish soap to the bowl and fill with water so bubble form.
  4. If you’re using waterproof letter prompts, put them in the water.
  5. Scoop away excess bubbles if you have too many, then blow up the balloon through the casing.
  6. Instruct or show your child how to pinch and release the opening of the balloon to control the flow of air.
  7. Have them fetch a letter from the bowl, submerge just the tip of the casing, and release some air while drawing the letter!

Discussion

Though this is a very fun activity because every kid would love bubble writing, it also sneaks in a lot of different types of learning. Not only does it support letter forming and recognition, but it also engages fine motor muscles and encourages coordination skills. Since blowing up the balloon is easier with the casing mouthpiece than without, it encourages independence and confidence. Setting up these types of unique activities encourage creative thinking, ingenuity, and resourcefulness.

Earth Day Multimedia Spin Art

Create beautiful and unique Earth Day spin art with your kids, while also learning about different environments on our planet. This project gives a twist to typical spin-art by adding glue at the end, which is then used to affix sand, dirt, and baking soda to give your Earths an intriguing texture and to spark conversation about the different environments on Earth!

Materials

Method

  1. Cut paper to the size of your spin-art box and affix to the spinner
  2. Prepare green and blue paint to your liking. You can also experiment with adding a little water to thin the paints and see what different effects you get.
  3. While spinning, drop, pour, or drip paint onto the paper.
  4. When you’re happy with the paint portion, squeeze about a teaspoon of glue right in the center of the spinning paper, then turn off the machine.
  5. Sprinkle sand where you want to create a desert, dirt where you want to create a continent with fertile land, and baking soda on where you want frozen tundra.
  6. Shake off excess, let dry, and admire your work!

Discussion

My four year old really enjoyed this whole process and made six spin-art Earths in one sitting. We discussed where on (actual) Earth exists deserts, temperate and tropical forests, and tundra, some of the animals that live in those environments, and what it’s like to live in each.

We also made our own spin-art box together, which added a lot to the experience for her. If you’re interested, check out our DIY spin-art box here!

Make your own Spin Art box: Basic circuits for kids

Teach kids about basic circuits and exercise their ingenuity by creating a DIY spin-art box from a cardboard box, motor, wire, and a battery!


Materials

  • Cardboard box
  • Scissors or box knife
  • Hobby Motor (The motors we have are no longer available, but this is a nice set that also includes, among other things, a battery holder, wires, and switch.)
  • Batteries (use correct voltage for the motor)
  • Duct tape (or a super strong tape)
  • Switch (optional)
  • Paper
  • Paint
  • Eye dropper or squeeze bottle

Warning: Spinning cardboard or paper can cut you, be careful. When working with motors and batteries, follow all directions as outlined by the supplier to ensure your are using their product correctly and safely.

Procedure

  1. Cut off the flaps of the cardboard box, trace and cut a large circle from one of them, marking the center of the circle.
  2. Set up your circuit with the motor, battery and switch according to the motor’s directions (i.e. Make sure you are using the right battery for the motor). If you don’t have a switch you can connect and disconnect the battery to turn it on and off.
  3. Mount the motor in the center at the bottom of the box with the motor shaft facing up. Depending on your motor’s casing, it may need to be mounted from the sides as opposed to the bottom because sometimes the back end of the shaft is exposed and will create friction on the box when running. This may be challenging, but it is exactly why you are making your spin-art box with your child instead of buying it- problem solving and creativity. We’ve done this several times and each time we try to think of a new way to mount it, including recycled Styrofoam blocks, a toilet paper roll, or one of the other flaps from the box.

  4. Poke a hole in the center of the cardboard circle you cut and set it on top of the motor shaft.
  5. Place a piece of duct tape over the shaft, pinch so it sticks to the shaft, then flatten the rest onto the cardboard.
  6. Test your set up, making adjustments if necessary.
  7. Cut your paper so it fits into the box, if necessary, then gently tape it to the spin platform.
  8. If you’re using poster paint or acrylics, water them down a little so they are more fluid.
  9. Turn on your contraption and squeeze paint as it spins!

Creating your own toys with your children fosters creative thinking, independence, and pride in one’s work. It also helps reduce waste and clutter in your home. Once you are done playing, you can dismantle your spin-art box, and reuse the motor and battery in many ways. Then, if you want to do spin-art at another time, set it up again!

Here are some projects from our site where you can reuse the motor:


Grapefruit, 5-geranoxypsoralen, and medications

This is 5-geranoxypsoralen. It’s found in many citrus fruits, but at an especially high concentration in grapefruit.
🍊
When you take some medications, or eat food, or drink $12 fresh-pressed juices, or lick hallucinogenic frogs, etc., an enzyme called cytochrome P450 alters some of the foreign molecules you ingested so they are more easily cleared by your body (AKA pee it out).
🚽
This is one of the first steps in your body’s built-in detox system (so yes, your body detoxes the detox juice you just drank 😉). 5-geranoxypsoralen, however, inhbits cytochrome P450 (specifically CYP3A4), which means that if you drink grapefruit juice, the enzyme cannot modify those molecules to clear them. This is usually fine unless you are taking certain medications.
💊
When you are prescribed a medicine, the dose takes into account the amount that will be lost by cytochrome P450. But, if cytochrome P450 is knocked out by the grapefruit juice, it will increase the effective amount of medicine your body will get, sometimes with toxic side effects.
😱
So, PSA, always check your medications’ labels for warnings about citrus juice. Common contraindicated drugs are Lipitor (atorvastatin), Buspar (buspirone), and Uceris (budesonide).

IKEA Flisat Table to Light Table Hack

This is so simple that I hesitated posting it because, well, you’ll see! But this is by far the easiest way you’ll find to make your Flisat table (or any two plastic bins!) into a light table!


Ok get ready for it. Take a bin and put some fairy lights in there:

Put the other bin on top of it:

You’re all set! Have fun with your new light table! It works like a charm!

Magnetic Slime

This little project feels like something out of a sci-fi, which perhaps is why I love it so much. Add some magnetite powder to your next batch of slime, get a strong rare earth magnet, and your kids (or you) will have a blast making zombie worms and magnet eating monsters- straight out of the movies!

Safety: Do not ingest any part of this project. Do not use any of the materials around small children or children who put things in their mouth. Too much iron is poisonous and it should not be ingested in this form. Rare earth magnets are very strong and can pinch fingers, be careful when using them. Magnets should never be left around small children who could ingest them. Do not use magnets near electronics or credit cards. The magnet in the video has a pulling force of 48 lbs. This was more than sufficient. If you are doing this with kids, do not use a more powerful magnet and only use one magnet at a time to avoid pinched fingers.

Materials

Procedure

  1. In a bowl or cup, dissolve the 1/8 tsp borax in 1/4 cup hot water. Set aside.
  2. To a different bowl, add 1/4 cup glue, 1/4 cup water, and 3 tbs iron oxide powder. Mix well. (Note: The powder will stain skin, so try not touch the iron oxide with your hands at this point, wait until the borax solution is mixed it. If you do get it on your hands, dish soap washes most of it off.)
  3. Slowly add the borax solution to the glue mixture and mix well.
  4. Take the slime out and knead with your hands till it is smooth. If it feels sticky, dip it in the extra liquid in the bowl and knead again.
  5. Start playing with the slime and magnet!

The Science Behind Slime

The glue contains a long molecule called polyvinyl alcohol (PVA). It is a polymer, which is a molecule that contains repeats of a subunit molecule (for example, “A” is a subunit and “AAAAAAAAAAAAAAA” is a polymer of A). Borax (sodium tetraborate) is a small molecule that can stick to parts of the PVA through hydrogen bonds. This means one side of the borate molecule can stick to one strand of PVA, while the other side of the borate can also stick to a different strand of PVA, creating a bridge between the two PVA strands. This is called crosslinking.

Having many crosslinking sites usually makes a polymer more rigid, but the interesting thing about borate/PVA crosslinking is that the bond is transient, meaning it can easily break and reform somewhere else. This causes the slime to act kind of like a liquid and kind of like a solid. If given time, the PVA can ‘flow’ as gravity pulls and breaks the borate/PVA crosslinks. It acts like a slime instead of a true liquid because as the PVA molecules pass by more borate, they can momentarily bond to borate and another strand of PVA, slowing down the flow. If you pull the slime fast, you break all those bonds quickly, allowing the slime to act like a solid momentarily.

The Science Behind Magnetic Slime

The iron oxide powder in the link above is magnetite, which is a natural mineral made of iron and oxygen. Like many iron-containing compounds, it is attracted to a magnet.

The iron oxide particles in the powder will become suspended in your slime matrix. As the particles are attracted to the magnet, they will pull the slime matrix with them, causing a whole section of the slime to move with it. This makes for some really cool effects!
