In this video tutorial, viewers learn how to do a sodium and water experiment. Sodium is a silver metal that is very reactive. When exposed oxygen in the air, an outer coding of sodium oxide will form. Simply drop a piece of sodium into a cup of water. When dropped in water, sodium reacts to form sodium hydroxide and hydrogen gas. The sodium will constant move around in the water. Sometimes the heated reaction will cause the nitrogen gas to ignite. Under the right condition, it may even cause...
In this video, we learn how to extract sodium to make sodium metal. First place soup can in a pot of water and place the sodium mixture into the can. Place a cap on top and leave it on while the can is cooling off. It should create a tight seal until you will be able to open it. Once you can open it, pour mineral oil on top of the sodium. Filter out this mixture to find the chunks of sodium that is in the mixture. While wearing gloves, take out the sodium and place it into water to see if it ...
If you've ever used a heating pad or hand warmer, you essentially know what "hot ice" is. It's supersaturated sodium acetate, and it's actually fairly easy to make at home out of sodium acetate crystals. You can also make it out of vinegar and baking soda (directions at the bottom of this article).
In this video tutorial, viewers learn how to make "hot ice". Users will need sodium acetate. Begin by putting the sodium acetate into a pan. Add a small amount water to the sodium acetate.

Ever wondered how science could turn out to be fun? Here's how: take a piece of paper with a mixture of sodium nitrate and sugar. When heated, sodium nitrate releases oxygen and burns sugar. Sugar alone cannot burn fast. If you want faster results, then take sodium nitrate with sulphur and some reactive metals. Add some coal to it for a faster result. This will help you burn some useless pile in quick time.
Sodium (chemical symbol Na) is an interesting element. It reacts in contact with both oxygen and water, and several sodium salts are used to produce a yellow color in fireworks.

Then place the pan on a stove and turn to medium heat. The Sodium Acetate Trihydrate will start to melt. In about five minutes when it has melted fully, add 25ml of water. Let the solution simmer for two minutes while...
Chlorine gas is a very useful oxidant, which was first introduced as a toxic weapon by the German Army. Even today, it's still used as a weapon, most recently in the Iraq War by insurgents. But chlorine gas has more useful (and less lethal) applications, and if you want to learn how to make some at home, NurdRage has the answers.
I have a weird fondness for the texture, if not the taste of Velveeta (and Kraft American cheese slices). No other cheese has quite the same amount of slip or smoothness and manages to stay that way, undoubtedly because Velveeta contains sodium alginate, an algae derivative that helps it stay so silky-smooth even as it heats up. It also contains a high level of protein-to-fat ratios, which is what makes it a champion melter.

Do this again with cobalt chloride and watch the crystals start to form. Watch these grow and ...
Two college students; Kevin Martin and Joey Smokey introduce the concept of Molar Mass. They start of by explaining what molar mass is, which is the relationship of a mole and a gram, it totals up the weight(in g)of a molecule. An example: say you have this compound, Sodium phosphate (Na3PO4). You know you have three sodium atoms, one phosphorus atom, and four oxygen atoms. You basically find the weight of each atom, if you have three sodium atoms, you multiply it's atomic mass by 3 (the numb...
This is a great video presentation of how Sodium Potassium Pump can maintain a voltage gradient across a cell. It also discusses various things like the differences between positive and negative charges and positive and less positive charges etc. The video tries to explain a lot of things happen within a cell when you fluctuate the voltage of sodium as well as positive and negative ions within a cell. You must watch it yourself to see the changes happen within a cell when you make some changes.

These are electrolytes and they will transfer energy through the pickle. Place a pickle on a glass plate and hook it up with an AC power cord with a nail on each end as shown in the video. You must have protective gloves on. Poke the nails on each end of the pickle and hook up the cord to the power source. The pickle will start emitting light which i...
This video is a discourse about saltatory conduction in the neurons. According to the author, it begins with the opening of a gate on the membrane of one of the dendrites of a neuron, and positive charge enters through this gate. The positive charge spreads throughout the cell, and gets dissipated as it spreads, so that, by the time it reaches the Axon hillock of the neuron, it is left with very little potential. However, the potential which results from the simultaneous excitement of many de...
