Hydrogen is an explosive gas in contact with oxygen and at high temperature.
This is unsafe because the small scale experiments done by classes are only producing a small explosion (the POP noise), whereas an increased amount of concentrated hydrogen can cause a larger scale explosion, which might be very unsafe. Happy learning! :)
There is a loud pop noise depending on how much hydrogen is present. The more hydrogen there is, a louder pop will occur.

Yes it does. However, it takes a much longer period of time to get the magnesium to give off hydrogen particles. After a solid 45 minutes you might get a pop, but it's part of the Alkaline Earth Metals which means yes... it will eventually pop.
Animal testing has changed a lot in the past centuries. When Galen disected pigs and goats in the 3rd and 4th century b.c. greek was called vivisection. Animal testing is pretty much the same thing except without disection.
