Now i am ready for the next test with Mercury.
Before 2 days a friend gave me 1/2 kgr of Mercury. I found a place far from people and without any metallic buildings near it. I will take a pyrex with dimensions 25x25cm, i will fill it with soil and i"ll put inside it the Mercury. After it i will dig a hole at 20...40 cm depth and i "ll put inside the ground the pyrex. I will cover the hole and the test area is OK.
Maybe Max has something to tell me about attentions!!!
Regards
