Creating a battery from a lemon is a common project in many science text books. It is not easy to create one of these devices. This video clip demonstrates how to make a lemon battery and use it to light an LED and operate a calculator. I will try this lemon battery experiment by myself.

Do you know how to swing a baseball bat or strike with a sturdy stick? If you do, then you will not have problem to use this unbreakable umbrella as a weapon for defence. The Unbreakable Umbrella from Real Self Defense works just as well as a walking stick or cane but does not make you look funny or feel awkward. It whacks just as strong as a steel pipe but it weighs only 1 lb. and 9 oz. (710 g). It can even support the weight of a person standing on it. Cool? What are you waiting for? Go to get one for yourself or your love one.

How many layers of tissues does it take to stop a bullet? Here is an experiment from Hey! Spring Of Triva. It is in Japanese language but we are lucky to have Japan Probe translate it for us.
Japan Probe said “The answer is about 2500 tissues. Their team counted each layer of tissue that the bullet made a whole in, determining that the 2354th tissue was without any damage. Of course, the impact of the bullet knocked back the tissues pretty hard, so anyone wearing a 2500 tissue vest that gets shot by handgun probably won’t be pierced by the bullet, but they can expect some injuries.”
