This is a fun little project that little ones can do too.
You'll need:
An empty clean water bottle
Glue
Paintbrushes
Confetti
Glowstick style flashlight
Colored duct tape
Modge Podge
Start by coating the outside of the bottle with glue
Then coat with confetti
At this point I would add a thick coat of Modge Podge (optional let dry then add a second coat). The confetti falls off somewhat easily if you don't.
Add the glow stick flashlight (I got mine at walmart $4.44) And secure with colored duct tape.
