We had fantastic fun this week creating our own foaming monsters!
First we decorated the bottles to look like scary monsters and then the fun started. We half filled the bottles with vinegar and added a big squirt of washing up liquid – our monster was now full of a green foamy liquid in his belly. Next we wrapped up some bicarbonate of soda in a piece of tissue – we went outside and added this into our monster….we watched and waited!
It was fantastic fun and there were lots of squeals of excitement and delight as our monsters started to explode foam everywhere! we can’t wait until next week to see what we will do next.
