Energy Ball

A great device to use when describing open and closed circuits

  • Energy Ball
    Item #: WENB-250

    $4.99 In Stock

Usually ships out the next day.

Recommend for 8 to 9 years with adult supervision.

This is a great little device to use when describing open and closed circuits. This 38 mm (1.5 in) ball contains two small metal electrodes. When the electrodes are touched simultaneously, the Energy Ball flashes and makes a buzzing sound. A great group activity is to have the participants hold hands. Have one participant touch one of the electrodes while another person at the other end of the circle touches the other electrode. Two people can touch the electrodes and make the Energy Ball buzz as long as everyone around the circle is holding hands. Recommended for children ages 4 and up.

Product FAQ

How many people can “connect”? 
This is a fun experiment to try.  We gathered up the entire staff of Steve Spangler Science outside, held hands in a big circle, and it still worked!  As soon as we came back inside, the nerd side came out of us and we started hypothesizing about how many people it would take for the ball to not work.  If such a simple activity gets a handful of adults into a discussion about their beliefs, imagine what would happen to your little scientists.  You wouldn’t believe some of the ideas that they would come up with to support their hypotheses.   It might also be a great activity to see who admires who and a great excuse for little lovebirds to hold hands.

While the ball worked, it was difficult for kids to make sure and place their hands on the small metal strips. If their fingers shifted in the excitement of the moment, it didn't work.

We used this as a time filer at my daughter's 1st grade Fall Party. It was a hit with the kids.

Fun for adults too!

The Louisiana Children's Discovery Center had a great time at our "Super Science After Hours" event and these energy balls were awesome! Even our adult volunteers were amazed. They were touching noses & chins to complete their circuits. So fun.

Thanks so much for this product. It is just what I was looking for my daughter's 4th grade class. She will incorporate it into a lesson on electric circuits. Special thanks to Dj or Bj? in customer service, for helping me with an address problem on my order it was my fault and he corrected it for me. The product arrive in three days just fine. She will be using it this year. Also thanks so much for the sup rise gift Great fun for my grandson! Thanks again

My students had a ball using the energy ball! They thought, at first, it was the amount of people, that made the difference. It was great to just sit back and watch/listen to them think!

It was great to demonstrate open and closed circuits!

Science without even knowing it.

The kids thought it was a "dumb" eye. And yet the spent an hour (six kids total- keeping one kid busy for an hour is hard but six of them at the same time- pretty good!) playing with it. Seeing how it would stop and start. A neat experiment without even knownig they were learning something. Pretty cool.

A bit disappointed

I was not impressed with this energy ball.
There are two exposed electrodes (small strips of metal) on the exterior that need to be touched in order to complete the circuit.
Not worth $5.
I ordered 2, and one did not work.

So great for so many experiments! My daycare kids and grandchildren are having a ball (no pun intended!)with it. And I'm so glad you included a catalog, we'll be ordering again for sure!

Halloween spooky eye

Thanks to Steve Spangler, I'm know as the science mom. My son's 4th grade class just finished studying electricity in science so it was great to bring in the eyeball (a bloodshot eye that I drew on the ball)for Halloween. We got as many as 26 kids to make a closed circuit and they really thought it was cool when one person "opened" & "closed" the circuit! I'm sorry I didn't video their excited reaction! My 6th grade son's class had fun with it too, but I never asked the girls goup to join hands with the boys group, 'cause girls are icky :),so the most we got there was a 14 person closed circuit! Time was also a factor, because I had the OOZING pumpkin (elephant toothpaste)experiment for them to do too. I wrote a short story to coorespond to the oozing pumpkin, then everyone got to "ooze" their own mini pumpkin. I have photos of that too if you're interested. thanks for all the cool stuff!
