The waiting little girl, soon joined by a second girl, asked. "Do you have something gross?"
"what was that?!" I replied.
"We need something gross. We're making a potion."
I thought for a moment, went into my house and peeled the silicone stickum stripe from a children's book that came in a box of cheerios. I rolled it into a small pea sized blob then dropped it into the girl's open palm.
"It's an artificial booger." I stated.
"An artificial booger. What's that?" Asked the second girl, recoiling from the first girl's booger laden hand.
I told them the source of the marvel of modern science. Satisfied, they wandered off.
I hope the potion works.
