A little fun for the weekend:
Find a dandelion, break it off and use the milky stuff in the stem to draw a design on the hand.
Rub the petals over the design.
There you have it, one yellow dandelion tattoo!
It will turn brown after a few hours. I'm not sure if that's from a chemical reaction or (ah-hem) dirt sticking to the tattoo? I'll leave that for you to figure out.
It washes off with soap. But don't try the same to your clothes. (It will stain them.)
