Well, I count myself fortunate enough to have been able to be exposed to a lot of chances to “tinker” and learn but this experience would have been right up my alley, I think, as a child. I did have my share of tinkering camps, including one at which we built the equivalent of a rail gun using leftover telephone wire, pencils and a large battery. It was capable of sinking a needle into a cinder block.
This kind of encouragement to experiment, try, fail/succeed is something that I think is sorely lacking these days. It can be amazing to see the innovative solutions kids come up with for forts, games, and building things. Check out the video (and, as usual, the TED Talks program always seems to find these nuggets of brilliance).
