In this video, we learn how to make Ferro fluid. This is a magnetic fluid that you can easily make at home. To do this, you will need: laser jet toner, rare earth magnet, and some vegetable oil. Now, pour the toner into a cup (50 ml), then put 2 tbs of vegetable oil into this cup as well and stir it together until you have a thin consistency. Now, transfer into a smaller jar so you can handle it easier. Now test this fluid by taking the earth magnet and putting it to the bottom of the jar. Now,...

An in-depth explanation of the structure of the hemoglobin molecule, the process by which it binds with the oxygen in the lungs, how it dumps the same oxygen molecule at the appropriate location in the body and how carbon-dioxide gets attached to the hemoglobin molecule are the topics which the narrator in this video explains with diagrams and a few equations. To clearly understand the concepts, cursory knowledge of the following topics is required: * Equilibrium chemical reactions, * The...

In this video, we learn how to make lightning with a spoon and a balloon. First, you will need to gather a spoon and a balloon. Once you have these, blow up the balloon then tie it on the end so it's sealed. After this, rub the balloon on your hair and then slowly move the spoon towards the balloon. Turn the lights out and watch what happens. You will see sparks of electricity start to appear between the balloon and the spoon! This is great to do with children or as a quick experiment to show...

Want to know why the sky is blue during the daytime and red during the evening and morning? A simple experiment is all that is needed. The ingredients required for the experiment are simply hydrochloric acid solution, sodium thiosulphate, a torch which produces white light, water and a few beakers and tubes. By carefully adding measured quantities of the chemicals above in water to form a suspension of sulphur particles, and then focusing the white light through the mixture at proper...

In this tutorial, we learn how to make verdigris with copper and vinegar. Verdigris is a compound of copper that is blue and powder. You will need: copper metal, vinegar, a big jug, and a small beaker. Now, place the small beaker inside of the jar, then fill the bottom with vinegar. Next, put the piece of copper metal inside of the jar making sure it sits inside the small beaker. Seal this and put it in a safe and dry place. Leave it for a good month, then when you come back you will have a new...

In this tutorial, we learn how to make a chemical indicator from kitchen items. First, make an indicator by grabbing some red cabbage and some vodka. Now, heat up some water until it's boiling, then place a smaller beaker inside the water with vodka inside of it. Place the red cabbage inside of the smaller beaker, then stir it up and let sit for 10 minutes. A lot of the color will come out with the cabbage being inside of the alcohol. After this, pour this into a storage bottle and pour the...

Have you ever wondered what the decomposition of rotting food looks like? Probably not... but now you do. Below: 13 days of time-lapsed, maggot filled rot. Be prepared. You might be inclined to skip lunch today.

National Geographic recently published a retrospective of the lovely Jane Goodall, one of the world's most accomplished conservationists. The feature includes every image of Goodall to ever appear in the magazine for the past fifty years.

Ok, so first Periodic Tables demonstrates how a McDonald's cheeseburger breaks down in your stomach during the digestion process. Everybody has hydrochloric acid in their stomach, so drop a burger in acid and you can see it happen before your eyes (minus the amino acids a human stomach would supply). Seems innocent enough. Here's what happened after 3.5 hours:
