How To: Make a storm inside a test tube

This science experiment will show you how to make a storm inside a test tube. This video tutorial will demonstrate the process of making the miniature thunderstorm inside a test tube with just a few common chemicals. All you need for your very own thunder storm is a glass test tube with holder, sulfuric acid, ethyl alcohol (ethanol), potassium permanganate, glass dropper, measuring spoon, and please wear safety goggles. Sparks and pops occur completely random, just like in a real thunderstorm!

How To: Make maganese heptoxide (permanganic acid)

This video tutorial is in the Education category which will show you how to make manganese heptoxide (permanganic acid). This procedure is extremely dangerous. Manganese heptoxide is an extremely powerful oxidizing agent. It has the ability to set fuels on fire from mere contact. Get an old dish and put a spatula full of potassium permanganate on it. Add a few drops of concentrated sulphuric acid. A green liquid is formed which is the manganese heptoxide. Now you can add any fuel like butanol...

How To: Eat foods high in potassium

Potassium is an important metal for keeping your cells alive and can be found in many foods, including fruits, vegetables, and meats. Potassium is a mineral that helps maintain normal fluid balance in your body, helps control blood pressure and reduces your risk of kidney stones. Potassium is particularly high in foods like bananas, sweet potatoes, yogurt, yellow fin tuna and soy beans. Try these tips for buying foods rich in potassium in this healthy nutrition how-to video.

How To: Make potassium trichromate

In this how-to video, you will learn how to make potassium trichromate. You will need potassium chromate and dichromate. It is easy to go between the two. You can add a base to the dichromate to make the chromate. It will go from orange to yellow. The trichromate can be produced. You will need nitric acid, potassium dichromate, and sodium disulphate. First, make a solution of sodium sulphate. Take a long test tube and the potassium dichromate to it. Add double the volume of concentrated nitri...

News: Potassium Chlorate—How Pyromaniacal Mad Scientists Take Care of Cockroaches and Pesky Gummy Bears

Pyromania is definitely nothing new on WonderHowTo. From flamethrowers and hydrogen fireballs, to flame-making pistons and wine corks, to simply burning steel wool fireworks and DIY smoke mix, we've covered it all. But when pyromaniacal mad scientists feel the need to release some tension in the lab, gummy bears and cockroaches become the victims of euphoric oxidation by way of molten potassium chlorate. A recent video by famous YouTube chemist NurdRage shows one of mankind's most despised cr...

How To: Make sodium bromate & potassium meta-periodate

This video tutorial is in the Education category which will show you how to make sodium bromate and potassium meta-periodate. This experiment uses toxic chemicals and releases harmful gases. First you have to make a saturated sodium bromide. To this solution then add a small amount of potassium dichromate. The solution now becomes concentrated. Then make the circuit as shown in the video. You need a 3 - 5 ohm resistor in order to reduce the current. Then let the cell run for around 6 hours. S...

How To: Make iodine easily

In this video, we learn how to make iodine easily. You will need potassium iodine and sulfuric acid to make this. First, add the acid into the potassium iodine slowly. After you add in each part, swirl the beaker slowly so it gets mixed together. After you have added in all of the potassium, you will place this into a beaker filled with ice water while you add in more, because the mixture gets really hot. When finished, you will end up with a mixture that is iodine and nothing else. Fill with...

How To: Use a sodium potassium pump

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.

How To: Understand saltatory conduction in neurons

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...

DIY Rehydration Drinks: How to Make Your Own Electrolyte-Enhanced Water for Cheap

While it's easy to make fun of water with "electrolytes," there's actually some science behind it. Despite the name, electrolyte-enhanced water isn't all that high-tech, it mostly means that it's been infused with vitamins and minerals such as potassium and sodium, which are very helpful in preventing dehydration. Unfortunately, electrolyte water isn't especially cheap, and compared to the tap, it's downright expensive. Luckily, there's a few recipes out there that can help you mix your own e...

Classic Chemistry: Colorize Colorless Liquids with "Black" Magic, AKA the Iodine Clock Reaction

Want to make boring old colorless water brighten up on command? Well, you can control the color of water with this little magic trick. Actually, it's not really magic, but a classic science experiment known commonly as the iodine clock reaction, which uses the reactions between water and chemicals to instantly colorize water, seemingly by command. You can use different colorless chemicals to produce different colors, and you can even make the color vanish to make the water clear again.

How To: Fertilize your fall lawn

John White from Southwest Yard and Garden teaches viewers how to fertilize and care for their fall lawn. Fertilization is recommended at 1 pound per month. As you reach September and October, reduce your nitrogen to 1/4 a pound and as October comes around reduce this even further to about half a pound. You will need turf fertilizer and on this package there will be three numbers in the order representing nitrogen, phosphorous and potassium. In late fall you will want to use a fertilizer with ...

How To: Make a dye-sensitized solar cell with titanium dioxide and anthocyanin

Discover the power of raspberries! Literally. In this NurdRage science video, learn how some crushed raspberries and some titanium dioxide (TiO2) can create a powered dye-sensitized solar cell. Inside a raspberry is something called anthocyanin, which is a flavonoid pigment. Commercially purchased solar cells are way more powerful than this DIY solar cell, but with a little improvement, who knows. Nurd Rage also lets you know how this works.

How To: Make manganese dioxide electrodes

Various electrochemical reactions requires that anodes do not degrade when used. Carbon is cheap, but degrades easily and platinum is extremely expensive. In a previous video, you learned "How to make cobalt and manganese nitrates", and you saw that titanium could be used as a cathode, but not as an anode due to an effect called passivation.

How To: Use wood chips in the garden

Chopping up downed trees and sending them to the landfill isn't ideal. It's better to use them as firewood or have them chipped up and use them as mulch material or for a walkway. Never combine woodchips with the soil because they rob the soil of nitrogen, phosphorus and potassium but they're great walkway material and will gradually break down providing nutrients for the soil.

How To: Clean your shoes with a banana
