Big Toothpaste Eruption from Fallout Shelter Hole, Giant Balls, Mtn Dew, 7up, Coca-Cola vs Mentos

#Shelter #CocaCola #Mentos In this experiment, we dig a giant hole, place a Fallout Shelter–style container inside, and pour in Soda, Mtn Dew, 7UP, and Coca-Cola to prepare the reaction chamber. We then add the toothpaste mix and activate everything with Mentos to create a powerful eruption bursting out of the shelter hole. The setup fills, foams, and releases a huge pressure blast, letting us see which soda creates the strongest reaction. Experiment steps: – Toothpaste mix inside the pit – Sodas, Fanta, Mtn Dew, 7UP, Coca-Cola reaction test – Eruption and comparison Perfect for viewers who love giant reactions, pressure tests, and explosive science fun.
