Michael had a friend share the coolest craft/ experiment and it's definitely worth giving it a whirl. The kids will love it, and I don't even have children so I did it for myself.
My daughter is very much like me. Her mind is always working which seems to be a common trait among night owls. She's very intelligent, funny and creative but as such she gets bored easily. That was the excuse she used when we grilled her as to why she felt the need to commit an all out food coloring assault on our dog Lola.
