Mark Robilar has been chasing the elephant's toothpaste world record for a few years himself. He set a record in 2020, but kind of shanked it as you'll see in the beginning of the video below.
In September 2021, he attempted to beat his own record at a surprise party thrown for a kid recovering from a three year battle with blood cancer.
The "devil's toothpaste" demo -- an even more explosive and dangerous variant of elephant's toothpaste, the formula for which he keeps secret -- at 9:20 shouldn't be missed.
