I applaud teaching things like this but being in construction am a bit shocked with no gloves or safety glasses for children doing things like this.

Hi there I have been trying to down load the 6 step instruction but have failed. Can you maybe mail it to me.
Thank you


Very cool. But Elementary school? I'm surprised a fifth grader is strong enough to cut cans and do the other steps. Did you have to help much?
