Science at its very finest.
Filling Stretch Armstrong With Water Until He Bursts, In Ultra Slow Motion

This is a video of the Slow-Mo Guys filling up two Stretch Armstrong dolls with water from a garden hose until they explode. They do one just laying in the grass, and another while Dan lovingly embracing the doll. Haha — not so tough now, are you, Mr. Armstrong?! God, I still remember the first time I cut open a Stretch Armstrong and tasted the goo inside. It’s not a taste you soon forgot. Your mom screaming at you for the mess you made on the sofa either.

Keep going for the video, but the real money shots are at 3:55 and 6:40.
