How to get students join the team?

[SamMullen]

When we've run into problems like this, we've found that the easiest ways to get people who are really into first are to either:
drag in random friends, give them tools, and tell them to do something. They won't understand what's going on, but by the time they've figured it out they're normally already hooked.
or to look for kids in physics classes that have already had some experience building things. Kids with carpenters or construction workers, or if you're really lucky engineers for parents can be not only a great supply of already partially trained kids, but mentors as well.
