Balloon artist Larry Moss teamed up with a group of volunteers and school children to build a massive acrocanthosaurus.
Larry Moss is part of Airigami, a studio of balloon artists based out of Rochester, NY.
If you're not familiar with an acrocanthosaurus, it was a dinosaur that lived during the early Cretaceous period (about 146 million years ago).
The 20-foot behemoth was built using a real skeleton of the dinosaur as a guide.
It took the group four days to finish.
School kids from local kindergarten and first grade classes came by to learn how to twist balloons.
For a lot of the kids involved, helping build this massive balloon dinosaur was the first time they had ever twisted a balloon.
The acrocanthosaurus is currently residing in the Virginia Museum Of Natural History.
