Re: Slightly OT: Re: science teacher needs help

This is a demonstration for a 5th grade science class.


They have constructed a majority of the apparatus, but have been
stumped (me too) as to how to solve the trigger problem.

What level of technical expertise do you think 10 year olds have to
find a solution for a problem such as this?

It needs to be completed by Friday (as stated earlier).
