The Sciences Fair Nicks expirement

At the Science Fair I was looking for something to write about and I chose Nicks because it looked fun.Nick is in 6th grade. Nick's problem was "will putting extra holes in mentos make the geyser higher.?"Nicks hypothesis was"Putting4 untouched mentos then he poked 10 holes in the 4 mentos then he poked 20 holes in 4 other mentos Nicks hypothesis was" more holes in mentos will allow more bubbles to form and will result in a higher geyser. Nick used a gragh to show us his results, his hypothesis was not correct and was correct.It was both because the geyser did'nt rise right away,but it took a little while for it to rise.I like the experiment because he used mentos my favorite mints.The experiment worked best withmentos poked 10 times.
