Here’s a child making an astute observation:
The childcare center playground has a plastic fort with plastic slides.
With repeated sliding, there will be static electricity.
A child (age three) and I zapped each other.
Her: “Zappies!!” (touching my finger again to make it work.) “Where’s the zappies?”
Me: “Hmm, it worked the first time you went down the slide, but now it’s not working. Why’s that?”
Her: “You need to put batteries in your toenails.”
