Science "Experiment"

Last week during science we did a experiment using baking soda and also vinegar. We put the vinegar in first, into the tube. After that we added the baking soda and had to get back away. Straight after we poured the baking soda into the tube it cause a reaction. The vinegar and the baking soda rose up almost out of the tube. 

There was a video but there were some technical difficulties.
