Youtuber Mark Rober (Former NASA & Apple Engineer) is awesome. Last year he failed at making a giant slime volcano. Only reaching 60 feet, but still impressive. The bottom blew out. Mark spent the next year building a stronger, bigger container. 5 Ton giant beaker. He threw a party with a pool full of 26 million Orbies. Made a giant bubble party and set up everything for the huge explosion. Mark Rober makes Elephant Tooth Paste Slime with Hydrogen Peroxide, liquid Soap, Food Coloring & Yeast (Potassium Iodide). When the expanding oxygen gas gets trapped in the soapy mix, foam is rapidly created. Learn more by listening to our podcast.
