can this grow my pee pee?

@1234buckeyefan As a matter of fact, calcium is one of the important ions for the contraction of muscles, however if you want to grow your pee pee, I would not recommend eating pure calcium, because it will destroy the musoca of your throat and oesophagus!

[MrFlamez18]

is this pure calcium

?

@MrFlamez18 Sry for the delay in answering... I wasn't online for a long time....

To answer your question: Yes, it is pure calcium.

If you have a balloon, filled with hydrogen, the "plop" will be a nice "boom". If you mix two parts hydrogen with one part of oxygen and you give it some nergy (e.g. a lighter, a candle, an electric discharge...), you better don't stend next to it and you better protect your ears, 'cos that's gonna be a very loud and hot "boom".

why when you put water in a "eprouvette (sorry can't get the english word)"put in on the calcium piece, then it react. After you take a flame put it close to your "eprouvette" and it makes a "POP" why????

@isajen1 Calcium in water:

Ca --> Ca2+ + 2e-

2 H2O + 2e- --> H2 + 2OH-

The hydrogen leaves the test tube pretty fast. If you put a flame to the test tube's opening, it reacts with the oxygen from the air:

H2 + 1/2 O2 --> H2O

That reaction makes "plop", if there is only a bit hydrogen.

@XLuxrayX Explosion depends on if the metal gets hot enough that it melts and breaks up into pieces. Alkaline earth metals have a high melting point.
