They arrange crazy races all over the world, and wanted to see whether a race based around dangling from helium balloons was possible!
"It was a fairly indescribable feeling, wafting across Africa on a cheap camping chair dangling from a load of balloons," says Tom. "Sort of peaceful and terrifying in equal measure!"
Just with fewer dogs and a higher probability of a horrible violent deathy fall to be devoured by lions and stuff when you land!
Tom and his pals hope to set up a large-scale helium balloon chair race in the next few years. Save us a place!
