Things You'll Need
- Clean, empty soda bottle with cap
- Food coloring
- Baby oil
- Fast-bonding glue
A wave bottle makes a great toy and educational tool. Using supplies you have around the house, this kid-friendly craft only takes about 10 minutes to make. Teachers can use this in their classes as a hands-on demonstration of the mechanics of both waves and tornadoes.
Using clean water, fill a soda bottle about one-third full.
Add a few drops of the food coloring you desire and add the beads, glitter or sequins. Fill the rest of the bottle with baby oil.
Put glue on the inside rim of the cap and screw in onto the bottle securely. Wait until the glue dries before you turn it upside down.
Gently shake the bottle back and forth to make wave action. Moving the bottle quickly in a circular motion and then stopping abruptly once the water is swirling will produce a tornado or water spout effect.
