Togo science is just one of the educational toy they make. They also make recycled material toys in their Green Powered line and also mathematics with their calculator toys. This copter is meant to show your child how helicopter propellers work when spun at high frequencies. The air pressure they create because of their downturned angle while spinning stationary on the mid pole is what creates this phenomenon that was realized many decades ago. This knowledge has helped societies create amazing machines called helicopters. They are very useful flying vehicles that the military and police use everyday to save lives. This simple but useful anomaly has been used in countless systems to boost productivity in society and one very important one is the wind turbine. This device translates wind into energy to gain electricity to power our world.
