Crashing and bashing in the name of science.
Parents need to know that this interesting series -- which focuses on reworking existing technology in order to provide better products intended to protect people -- tests new inventions in large-scale simulations that usually require crashing and blowing up cars or other vehicles in a protected environment. The experiments sometimes fail, but the failures are looked at as stepping stones in the overall design and engineering process. The show will most likely appeal to older tweens and teens who are either a) interested in science or b) like to watch things get smashed up in a big way. Kids (especially teens of driving age) may need to be reminded not to engage in such activities themselves.
