I have seen these before and knew I could recreate them for the boys. It wasn't that hard and the bottles are very durable. Since the pompom box was such a success I had the time to test it out. Feel free to fill with small plastic fish, animals, or glitter.
What you will need:
Water Bottles
Pompoms
Colored Beads
Glue Gun & Glue
Water
1. Fill the empty water bottle with the beads and pompoms.
2. Fill with water leaving a little room on the top.
3. Place a few dots of hot glue around the thread of the bottle top.
5. Screw the top on quickly and securely, and voila a discovery bottle.

"Bubbles" said Caleb.
He liked to see what would float, and what would sink.
