Eye Spy Bottles!
You need one empty water/soda bottle, rice, confetti, buttons, penny, small toys, beads, erasers, foam shapes, candle, dice, pom pom, etc.
Put some rice in the bottle, then add a few items. Continue adding rice and items til the bottle is almost full. You need to leave some room for the objects to move and be found. Hot glue the lid and then have fun finding items and certain colors.
No liquid so you can take on the airplane!
