Got these more out of curiosity then anything. Little did I know they would be fun to explore the house with. The wife always thinks I鈥檓 crazy for buying things that I don鈥檛 need. Once she seen how unclean our clean house was, they quickly became hers鈥ol. I can think of many uses for these. From the interesting things we could see to letting the kids play for hours. Best in darker places though.
