This is the 20-foot long (it looks longer to me but I've ridden real dinosaurs though so I should know) balloon animal Acrocanthosaurus built by balloon-twisting professional (and awesome dude to have at a kid's birthday party) Larry Moss and his team at Airigami for Virginia's Museum of Natural History. Because if there's two things kids like, it's balloons and dinosaurs. If there's three things kids like, it's balloons, dinosaurs, and eating their own boogers. *licking finger* Like homemade Play-Doh.
Hit the jump for several more shots and a time-lapse of the dinosaur being made. Which, for the record, is nothing like how God did it (he was into clay).
Thanks to Darth Jim and Elaynantravis, who agree they should have filled the thing with helium so I could ride him into the sky and eat clouds together.
