Mercury, the only common metal that is a liquid at room temperature, has been known and used since ancient times (1500 BC). Mecury is really beautiful and twinkly. But Mercury-containing materials are usually extremely toxic, it can be absorbed through the skin, especially through an open cut, so prolonged contact is NOT good.But now you can touch it everytime, everywhere you want without your gloves. And you can only do that in my app called “TAP MERCURY”.The gameplay is easy to know, you will touch mercury boxes with numbers from the smallest to the biggest in the shortest time. Let’s play and tell me who is faster. Enjoy it !!!
