There's Always Room For J-E-L-L-O

If you've ever wondered about the science behind the ultimate JELL-O shot, then you'll like this site!

Here are their conclusions:

Although the proportion of alcohol to be added to Jell-O shots is partly a matter of taste, the typical Jell-O shot recipe greatly underestimates the amount of alcohol that can be added to Jell-O while still maintaining the gelatin’s setting properties. As long as a minimum amount of boiling water is used to completely dissolve the gelatin powder (4 oz. boiling water per 3 oz. package Jell-O), an amount of 80 proof alcohol up to 19 oz. can be added and the Jell-O will still gel. With sugar-free Jell-O, the minimum amount of boiling water necessary is 3 oz., and up to 24 oz. of 80 proof alcohol can be added and the Jell-O will still gel.
