For our LED project we used these supplies: LED light, tinfoil, tape, holographic confetti strings, glass bottle, glitter, and a CD disk. We made this by first, putting a piece of tinfoil with glittr glued on it in the inside of the bottle. Then, we LED lights inside, and taped the battery pack on to the outside of the bottle. Then, we put a holographic CD on the bottom of the bottle, and taped holographic strings on the outside. We put the holographic CD on the bottom of the bottle, to reflect the LED lights.
