Expanding on what you're saying, I think it's important to get people to curb the knee-jerk soccer mom reaction "OMG MY CHILD IS MAKING BOMBS" and find out if the child is making bombs because they have a serious psychological problem, or they're interested in science.
One child needs a therapist, one child needs a chemistry book.
Speaking as the child who made bombs, and got the chemistry book :)
When we hear about a kid who got caught building a bomb these days we never think Wow - they'll make a great entrepreneur some day!
Maybe we should learn not to judge children too harshly?
