40' Balloon

This balloon was great value for the price - easily the largest balloon I have ever launched with my students. Came packaged well and worked as I expected! Sent our science experiments to 100K feet in the air!

I purchased 3 of these and told my little brother to hold on tight. He weighs 65 lbs. I was hoping that he would go into space, but unfortunately, when he was 10 feet off the ground, he let go, fell and broke his leg and now everyone is very angry with me. NOT recommended. Does anyone know where I can find balloons that attach to people or maybe a harness?
