The effect is not unlike the effect of breathing nitrous oxide, but this is
only from personal experience in a chamber down to 50m and to test my
nitrous oxide tolerance (and also to recognise the effect of nitrous oxide)
during training to use the gas. So either:

Put the trainee into a chamber, and take them down; this was a very
interesting experience, as it really demonstrated the difference between
people, and how easily affected some people were, as well as how little
control they had over their actions. Or just use nitrous oxide on someone.
