40 Pieces Science Party Balloons Decorations Science Latex Balloons Birthday Party Decorations for Scientist Lab Holiday Laboratory Supplies Decor

I love that these promote science. I'm a bit of a nerd, and had to get them for my son who among other things loves balloons. He wanted to reproduce an experiment from school with baking soda, vinegar and a balloon, so I got these cool science balloons. He loves them. I have to keep them stashed deep in my closet so he doesn't use them all at once! They'd be perfect for a science themed party.

Great purchase, good size and made for great decorations for bday party! Very happy with purchase.

Only a 4 star for the strong chemical smell. I would NOT recommend blowing up by mouth. I used our air compressor.With that said, they're big, and I feel like they're good quality. Perfect for our "nerd" theme party.

Used for decoration at a microbiologist graduation party. Super cute and loved them

Came as advertised. All balloons inflated as expected.

Durable, bright and long lasting. They made a great mini balloon garland and a bouncy seat for my 2 year old. The balloons lasted for a few weeks after they were blown up. Mom and kid approved!

My son loveeeed them!

Great balloons! The images and colors were perfect for my science party. Great thick quality. Filled with helium and lasted as long as I expected to. None popped while filling (or being beaten around by wind or kids). Would definitely recommend!
