Got them form my dad in his science class for demonstrations fo kinetic and potential energy. I'm sure the kids had a blast.

These ballons are super fun and entertaining for our toddler. They are loud and exciting, and fun to shoot all over our yard. I have purchased these in a store, however, these are higher quality and can be used over and over again.

I have an old rocket balloon set that we got when our kids were little. We loved it and used the balloons over and over. Based on the other reviews, I bought this brand and also the Toysmith brand refills for my niece. I wanted to compare them to see which was better. It turned out that both were about the same.

About half the balloons popped either the first or second time we inflated them. Those that did not die right away did not return to their regular shape, but were instead stretched out and rather floppy. Most of them did not make the squealing noise that they are supposed to make when flying around, and only a couple flew high in the air. Sadly, the Toysmith brand performed more or less identically, so I will have to keep looking.

These balloons are terrible! They are rolled over on themselves on the end, which makes them heavy, so instead of flying up in the air, they quickly fall over and go sideways. We've also popped several trying to fill them up enough to really make them fly. We discovered these (a different brand, apparently) at a concert in the park, and our kids loved them! These don't fly like those do. They're quite lame, and we're quite disappointed.

Kids love these rocket balloons. From 2 years old to 10 years old, they love to watch these rockets go. We have played with these indoors and outdoors and it is fun. Just wish there was an automatic pump that makes it easier for the kids to do it themselves.
