Huge foam volcano covers garden in world's biggest 'elephant toothpaste' explosionThis incredible footage sees a foam volcano of acid, soap and food dye take over a garden. The dramatic experiment was carried out by YouTubers Nick Uhas and David Dobrik - who were re-creating a similar attempt by NASA engineer Mark Rober. Known as the elephants toothpaste test - the mixture

combines and reacts before exploding dramatically - with the foam-like substance growing to an incredible size. In the YouTube footage, Uhas explained the science behind the experiment that resulted in 200 cubic meters of foam sp

grows larger and gets stuck in the soapy water. Bubbles are then created, which continue to grow. Uhas said: We start with 35 per cent hydrogen peroxide and we add soap and food coloring dye, we then add a catalyst potassium iodine in our case.
