Some things in this world just don’t mix... dogs and cats, oil and water, needles and balloons. Everyone knows that a balloon’s worst fear is a sharp object... even a sharpened, wooden cooking skewer. With a little scientific knowledge about balloons under your belt, you’ll be able to perform a seemingly impossible task... pierce a balloon with a wooden skewer without popping it. Piercing takes on a whole new meaning! Recommended for children ages 8 and up.
- 25 Latex balloons
- 15 Bamboo cooking skewers
- 1 sheet of sand paper
What does it teach?Learn all about molecules and polymers with this mind-boggling kit! You will amaze and surprise your audience as you literally skewer a balloon, but your new-found knowledge of the elasticity of molecules will make this an easy trick to perform!

I did this "Balloon Skewer" activity for the first time this past spring during the annual "Science Day" at our middle school, and it worked great. I, too, was impressed the first time I saw it done . . . so, you can only imagine how the 6th grade kids that I work with reacted to it.

Wow! I was afraid to do this the first time I did it, and the true emotion was mirrored on the faces of the scientists watching me... however; when the skewer went into the balloon the fear hissed out of our bodies just like the air escaping from the tiny opening made by the skewer! And the energy changed to excitement as they all were eager to try for themselves. With the exception of one mis-directed skewer we have done this 30 times with not one balloon popping! (My scientists are ages 5-9)
