My favourite part of science week was the volcano experiment that we did in class.
First we Mixed baking soda and the food coloring and then we quickly put in the vinegar to make the reaction.
The mixture expanded with bubbles. It had to go upwards since that was the only way.So it came up and out the top. It flowed all the way back down along the outside.
I liked this one the best because of the explosion!
