Glow sticks as travel night lights
I just discovered a wonderful hack while on vacation. We brought along glow sticks to play with on the beach after dark, but discovered they worked great as night lights for our 5- and 2 year old sons. They got to choose a new color each night, so it was exciting to go to bed. We got the bracelet glow sticks, so they wore them all night and it helped make an unfamiliar room much more comfortable!
