Science Fair

My Science fair Group did Coke Bombs.
The Groups members are Me (Conor), Cory and James.
We started with Pepsi and James dropped 2 mentos in a ran for it. I had to tie the lid on and then boom it only went 2 cm up an 5 wide. Pepsi was a failure so we had to put that in our log book.
So then Cory brought Coke Zero and me and James thought it would not even fizz. But it went better than the Pepsi it went 8 cm up and 1 m wide.
Then I brought coke and every one thought it would be best so James dropped 2 mentos in and ran i tied the lid up and then it only went 5 cm in the air and 50 cm wide so in fact Coke Zero is the best coke bomb but diet coke is the best but we did not test them
