Create Wave Bottles For Summer Fun

My kids are outside all summer long so when it rains I feel like I need to be prepared. One of our favorite projects is a wave bottle. We’ve made them the last three to four summers. The first time I ever made one I was in elementary school with my Brownie troop at COSI Science Center in Columbus, Ohio. I have loved them ever since! Very simple to put together and hours of entertainment for your kids!

You will need:

Empty water or juice bottle

Water

Clear oil (we always use baby oil)

Liquid food coloring

Hot glue gun and glue

Glitter (optional)

Beads (optional)

What you need to do:

1. Remove the label from your bottle. If it leaves any sticky residue we always clean it off with Goo Gone so that the bottle is totally clear. It does not matter what size bottle you use.
2. Fill your bottle approximately half way up with water.
3. Add a drop or two of food coloring and swirl your water around to mix it in. Add any glitter and/or small beads you would like.
4. Fill the bottle the rest of the way up with the oil

1. Run hot glue around the threads of your bottle and screw the cap on while it’s still hot. This will create a water tight seal for your bottle.
2. Once the glue has cooled, hold your bottle on its side and gently tilt it back and forth, creating waves!
3. Enjoy the fun!
