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.
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.
What is MnSO4 and MNO2, anyway? They are they molecular formula for Manganese Sulfate and Manganese Dioxide. And you can make one from the other. But how?
If you want to make some electrodes for electrochemistry, titanium strips are the way to go. It's rather interesting metal, and it's really hard, but can be cut with standard metalworking tools. Titanium filings are highly flammable, just like iron filings. But not everything is what it seems… this quick video on titanium and passivation electrochemistry tells why it makes it a bad anode if used without further treatment.
This video speaks to everyone who has ever bought anything online, or in fact, anyone who has ever bought anything period. How do you know what you're getting is genuine? Is it a fake product? Is it stolen goods? Is it impure?
In order to make manganese dioxide electrodes, you're going to need cobalt nitrate and manganese nitrate to do it. Making cobalt nitrate is fairly easy, but making the manganese nitrate is a little more complicated. But not impossible.

WhatsApp is a very popular messaging app on the Play Store, but unfortunately, tablet users have been left out of all the fun because WhatsApp only works on smartphones—until now.
The latest Google Play Services update has somehow broken major functionality in both Titanium Backup and Substratum. Titanium Backup has suddenly become stuck at zero percent while restoring, and Substratum simply fails to apply themes anymore. Both of these apps do require root, but they've slowly become essential to rooted users, especially since apps like these come into play when you're deciding what your next phone should be.
In this Education video tutorial you are going to learn how to draw the Lewis structure for carbon dioxide & methanol. Carbon dioxide is CO2. Oxygen atoms don’t bond together. So, carbon atom has to be in the center. Oxygen has 6 valence electrons and carbon has 4. Hence, carbon wants to form 4 bonds and each oxygen atom wants to form 2 bonds. So, two each electrons of carbon will bond with 2 electrons of each oxygen atom. The Lewis structure for CO2 will be ( …. O=C=O….). The 4 dots within t...
We all learn a simple description of photosynthesis in grade school but there are a lot more complicated process going on. Plants can utilize carbon at night and this description will explain a very advanced understanding of how CAM works.
If you're planning on doing some bondage knots, you better learn how to do it right. This video shows you how to properly tie off a titanium suspension ring for use in your bondage activities.

Watch this science video tutorial from Nurd Rage on how to make nitric acid. They show three ways to make nitric acid based on two different chemical approaches, both of which can be done using easily accessible materials.
Learn how to proof yeast. Yeast is used in baking as a leavening agent, which is what makes bread and pastries light and airy. Yeast reacts with moisture, sugar, and heat to create tiny bubbles of carbon dioxide which cause the dough to expand and rise. To proof yeast, you'll need yeast, sugar, moisture and warm environment.
The Google Play Store exists so you can download as many apps as your heart desires (and as your memory can hold). Sure, you may only use them once, but it's your choice—and isn't that what life is really about? With that said, the Samsung Galaxy Note 2 already comes with a ton of preloaded apps from Google, Samsung, and your device carrier, like Yellow Pages and Google Earth—both of which I never use. So why is it that Android won't let me remove or uninstall them?!
When it comes to global warming, most of us think of carbon dioxide emissions. While carbon dioxide is the most important greenhouse gas, carbon dioxide emissions have stayed constant for the last three years. On the other hand, methane, the second most important gas, has been steadily rising since 2007.
Everyone starts their mornings differently, but one common thread amongst the masses tends to be the consumption of coffee, albeit in many different forms—instant, pre-ground, K-Cups, Nespresso, and so on. And I'm sure that we all have our own preferred methods, as well.
If you have some dry ice, try this cool science experiment out. It's so easy, you have to try it, at least once! You just need a chunk of dry ice and some metal coins, like a half dollar (which is comprised of copper and nickel).
This reaction is between metallic magnesium and carbon dioxide. Magnesium reacts with oxygen in the air to form magnesium oxide, but when the only source of oxygen is from CO2 the reaction becomes much more energetic. The products are white magnesium oxide and black carbon.
Mr. G plays with chemicals and fire (what a surprise), for a really cool demonstration. An experiment you'll want to try, and probably can try immediately, as all materials (vinegar and baking soda) are likely in your house already. Exothermic reaction and gas displacement at its best!
Sulfuric acid is mixed with sugar, which is attacked by the acid. The final products are carbon, water vapor, and sulfur dioxide gas.
Sick of spending your hard earned money on the bourgeois bubbly water? Why spend extra money on bottled seltzer when you can make it at home? Plus, by using fewer plastic bottles, you can reduce your carbon footprint.
Amaze and amuse your friends with this fun magic trick! Using only vinegar and baking soda, which you may remember from some of the bottle-bomb-making videos elsewhere on the site, you can create carbon dioxide which, since it's heavier than air, can be used to invisibly fill a glass and then be poured onto a candle, extinguishing it without looking like it's done anything at all! No word on how long the gas will stay in the glass, so set this one up right before you want to do it and then hi...
This video helps us understand the organic molecules and elimination reaction. Take some sugar in a beaker. Sugar has 12 carbon atoms, 22 hydrogen atoms and 11 atoms of oxygen. The sulphuric acid is poured into the sugar and the color change is observed. The color of the sugar gradually changes into black. The sulphuric acid causes an exothermic reaction which releases a large amount of sulphur dioxide gas. All the water (containing hydrogen and oxygen atoms) is eliminated out of the sugar du...
Plants all around us capture sunlight every day and convert it to energy, making them a model of solar energy production. And while the energy they make may serve the needs of a plant, the process isn't efficient enough to generate power on a larger scale. So, scientists from the University of California found a way to treat bacteria with chemicals that turned them into photosynthesis machines, capable of generating products we can convert into food, fuels, and plastics.
