Today I stuck a toothpick into a balloon, and it didn't pop!
The tricks are:
Use a toothpick with a very pointy point
Use the relatively thicker point of the balloon (the rubber "spot" on the very top)
Lubricate the spot AND the toothpick with a small amount of petroleum jelly.
Push the lubricated tip gently into the lubricated spot (not too hard!), and rotate the toothpick as you push. Be patient -- as you push gently and rotate, the rubber will gradually move around the wooden point, and you'll succeed!
SCIENCE: Balloons are made of latex rubber, which is a loosely cross-linked network of long polymer chains. Look at the structure of latex rubber below, and you'll see why the rubber can move around the wooden point and still hold.
