Easter Egg Wack-a-pack Balloon Surprise! 2 Pack of 4 Self-inflating Foil Balloons- Various Designs

I bought I of these and only bbn one popped open with the balloon only half inflated. Very dissapointed.

These were a fun little item for the kid's baskets. However, not all of them worked. In fact, one of them oozed out a liquid into the floor. I am not sure if I just got and old or defective pack, but it was a little disappointing that they only worked about 75% of the time.

These are great. Kids love them. Just make sure you hit them on a hard surface, and immediately shake or sometimes they don't pop open correctly.

These are AWESOME!!! Had such a fun time doing Valentine ones with my grandkids....that we had to order the EASTER balloons! Pretty fun to watch them appear right before your eyes!!

Did not perform as described. Bummer for the kids! Dud.

We purchased these for a large Easter party with a bunch of kids, and we're tremendously disappointed that only one third of them actually worked correctly. The other two thirds either didn't insulate at all or they inflated somewhat but not enough to break open the outer packaging. We had a bunch of very disappointed children!

The ones that worked worked great! Unfortunately about 25% were duds.

Used these in a scientific demo for chemical reactions. Worked great!
