Styrofoam Balls

Styrofoam balls provide a creative way to generate lots of static electricity for all of your shocking science experiments. They're also great for explorations with density. Our workshop presenters use them to make static wands, density tubes, or as a new addition to their latest Tornado Tube invention! We take a 30 cm x 30 cm (12" x 12") bag and stuff it full of Styrofoam balls (that's about 4000 mL worth of styrofoam balls). Before you pick up the phone and call, the balls are roughly 2mm to 4mm in size (that's about 1/16 to 3/16 of an inch). Recommended for children ages 6 and up.

What's Included?
  • You'll receive 221,513 tiny Styrofoam balls measuring 2mm to 4mm in size. If we're wrong, please send us your official count and we'll make up the difference (it's a cheap way to get someone to actually count a whole package of tiny balls).
What Does It Teach?


Giant Static Tube - Rinse out a 1-liter soda bottle and let it completely air dry. Fill the bottle with 1/4 cup of Styrofoam balls and seal the bottle with a cap. Rub the bottle on your head (or better yet, your friend's head) or on a wool sweater. Observe the effects of static electricity on the Styrofoam balls!

Styrofoam balls for static bags Review by Allison Speer

We love using the styrofoam balls to make static bags - put a scoop of the foam in a zipper bag and zip; run a plastic spoon in your hair and then across the bag to watch the styrofoam balls jump and attract to the spoon. We send this as a take-home for kids after their electricity program and they love it! The only caveat - making the styrofoam bags on a dry day is a challenge...those balls want to go everywhere BUT inside the bag! (Posted on 4/30/13)

  • How big are they?
    These things are tiny! They measure about 4 mm in width.
  • What are they used for?
    The beads are used for two main areas of demonstration. First off, they are a great way to play with static electricity. Also, they help to explore the properties of density, especially when combined with our Tornado Tube.
