How rapidly were the cans opened ?

This seems to me to be the most important factor, one that they did not investigate.

Pull the ring quickly, rapid loss of internal pressure and the beer will fizz out.

Pull slowly opening it a crack, wait for the internal pressure to reduce and then complete the opening and little beer will be wasted.

I thought that most kids learned this with bottles of pop.
