World Balloon Modelling champion Mark Verge makes cool balloons for a living, but none cooler than this life size T-Rex. It consists of over 1400 balloons and took hundreds of hours to make but only a couple of days to become extinct. A previous version of this dinosaur took first place at the 2007 World Balloon Championship, and Mark shows us how it’s done. As he describes it “The Coolest Thing I’ve Ever Made”.
