My 8 year old just showed up bringing me his "concoction". He mixed liquid hand soap, chapstick shavings, shampoo, toothpaste and water to make his own "hand sanitizer". He says it works great "if you're in your room grounded and need to wash your hands".
Of course, we HAVE hand sanitizer - never in their rooms - but thought it was kind of cute that he created his own.
I know when I was a kid, my cousin and I would make secret potions - similar items mixed in (including perfume - EWW!) and we would actually DRINK it. So, he's doing better than I did as his is not for consumption! LOL
