Being the curious type, I did some more experimenting with the Mentos over the weekend. This time instead of the brand name soda, I decided to try generic soda.

The first test was conducted in the parking lot at work last Friday. The bottle was placed on the pavement and in went the Mentos. The soda jetted about 4 1/2 feet into the air and after a second or two the stream collapsed back on itself. Sethiya got it on video but it’s a bit more than 17 MB – not exactly a “reasonable” size. But a still shot, that’s not so bad.

During the Relay for Life last weekend, I launched a second bottle. No still shot yet, but this time the bottle was leaning against a concrete block and the soda stream went another six to twelve inches higher, possibly because the soda wasn’t falling back on itself.
