You only need a few supplies for cheap, easy hours of fun! Take a clear plastic container, light string(s), white tissue paper or wax paper, clear tape and some translucent objects.
Place the lights in the box (it is okay if cord sticks out). Line the inside of the box top with a thin layer of white tissue paper and attach with clear tape.
Plug in, put cover on and enjoy:). Let me know in the comments if you tried this and if your kiddos loved it too!
