elephant toothpaste

in elephants toothpaste first we had to put safety goggles on and some gloves on.After that we had to put in warm water with yeast then mix the yeast with the warm water.THEN WE ADDED THE YEAST AND WARM WATER MIXED INTO A TUBE WITH HYDROGEN PEROXIDE.AFTER WE POURED WE HAD TO QUICKLY RUN BACK AND WATCH THE ELEPHANTS TOOTHPASTE RISE AND GO BOOM BOOM.THEN WE GOT TO TOUCH THE TOOTHPASTE WITH OUR HANDS WITH THE GLOVES ON.

MY HYPOTHESIS WAS I THOUGHT THAT THE TOOTHPASTE WOULD FORM INTO A MASIVE BALL THAT LOKKED LIKE AND ELEPHANT.

I THINK THIS HAPPENED BECAUSE THE HYDROGEN PEROXIDE WOULD REACT TO THE YEAST AND WATER AND MAKE A MASIVE FIZZY THING.
