This is our second attempt to reach a 18 ft geyser. We had earlier only managed to get about 6 feet with 4 mentos in a 2 litre Diet Coke. This time we decided to use all 12 mentos in a pack.
We had to devise a paper funnel to make sure that all 12 tablets drops into the diet coke quickly. The reaction was instantaneous and we just can’t take our sweet time to do it. Nanzaro and Webster were too chicken to drop it — so Arkensen did it again; this time he was much more confident.
So how high does this look to you? Certainly more than 10 feet, maybe 12 feet I say. Amazing, it was great fun.
