Making Hydrogen and Oxygen at home

What is hydrogen.
Hydrogen is a very light gas. Hydrogen atom has 1 proton, 1 neutron and 1 electron. Hydrogen molecule has 2 hydrogen atoms.

How to make hydrogen and oxygen at home.

We can make hydrogen at home. Water has hydrogen and oxygen. By passing electricity through water we can split hydrogen and oxygen.

Here are the steps.

1. take two bottles.
2. make a slit in both bottles.
3. put wires in both bottles
4. fill them with water.
5. keep the bottles upside down in a large plastic container.
6. connect the wires to a 9 volt battery.
7. watch the hydrogen bubbling from the negative wire [cathode] and oxygen bubbling from the positive wire [anode].

Black Holes

What is it?

Black holes are remnants of a dead star. They have lots of mass. But they are very small. Black holes are mostly found at the center of galaxies. There is something called the event horizon, after crossing it, nothing can escape!

How much gravity does a BLACK HOLE have?

We do not know. We cannot measure it. But we know that it has Immense gravity and even light can’t escape.

What is gravity

Gravity is the tug between 2 objects. For instance, you and me ,we are pulling on each other, that is exactly why the sun and the earth always stay together.

My thoughts

If we could use the enormous gravity of a black hole and create a worm hole and then use that worm hole to travel to another universe, then we could see what is at the other end of the wormhole.

That would be sooper doooper coooool !!!!
