High quality, clear latex balloons that are perfect for any science experiment where you want to see what's going on inside the balloon. These balloons measure 11 inches in diameter and come in a pack of 100. You'll also receive an activity guide outlining a few of our favorite science experiments that use these balloons.
Screaming balloons review by Judy on 5/16/2013
Students love the screaming ballooon. We use the clear balloons frequently in our afterschool and school programs but always seem to find a handful that don't want to retain air very long. Appear to have tiny pin holes in them. Our local party stores do not carry clear balloons so we are glad that you stock them. It would be neat if you also carried large (3 ft.) clean balloons. Used one with a number of hex nuts as a demo before having the students do it, and they were very excited!
Clear balloons - screaming balloons review by Kara Cruse on 4/22/2013
I purchased 200 for a science camp for 135 children and so many popped or lost air right away that we ran out. Not cool!
Mrs. Russell review by Joyce Russell on 3/29/2013
Well, they are clear and that makes it nice to be able to see through, however; from the package of 100 I have had at least 25 of them pop when my "scientist put the balloon down, dropped it with the spinning penny inside, or just while holding the balloon. I wonder if the balloon is thinner for it to be clear. I also had a few with tiny pinholes in them and at least 12 that didn't hold air for more than 8 minutes.
clear balloons review by Deb Leedom on 2/8/2013
I was excited to find that clear balloons were available for purchase online, as I was having difficulty finding any locally. Our physical science class performed the centripetal force penny experiment, as well as the skewer- through-the-balloon demonstration. The students loved the experiments, but were visibly disappointed when many of their balloons failed to hold air throughout the 45 minutes of balloon-time. Several balloons had small visible holes and were losing air before being tied. But the point of the experiment was clearly understood in a fun hands-on way-which we love!!! Thanks!
Thank you for the feedback. We are looking into the problem that you had with the balloons. We hope to find the source and fix it ASAP.
