That's a whole lot of not toothpaste!
World’s Tallest Elephant Toothpaste Chemical Reaction Reaches 250-Feet

This is a video of ex-NASA engineer turned YouTube money maker Mark Rober (previously) setting the world record for the world’s tallest elephant toothpaste chemical reaction, mixing hydrogen peroxide, soap, and potassium iodide in a 5-ton flask with a resulting volcano that reaches a respectable altitude of 250-feet. Obviously, if right now you aren’t thinking, “God, I only wish I could have been there to sit on top of it when it erupted,” then I’m sorry, but there’s little chance we’ll ever see eye-to-eye on anything.
