Etching your own circuit boards is tons of fun, but etching requires strong chemicals to dissolve the copper plating on blank circuit boards. The normal ferric chloride solution works well, but can be expensive and leaves permanent stains. Luckily, we can whip up our own etcha ...more

If you've ever had teeth removed/minor surgery, you most likely received some laughing gas, or nitrous oxide. This gas creates a happy, lightened feeling, and causes instant laughter. In this article, I'll show you how to make some. BUT BE CAREFUL!!! DO NOT proceed in this exp ...more

Many people drink green tea for health reasons, and it's no wonder. This beverage is a superstar when it comes to antioxidant levels, and is being studied for its potentially curative properties on multiple health concerns, whether it's staving off the aging process or fightin ...more

It's a shame that one of the world's tastiest foods can be such a pain to prep. Most cooks are familiar with this conundrum: chopping or crushing garlic releases a pungent liquid that causes bits of garlic to stick your knife and hands, creating a messy affair. So what is goin ...more

Home chemistry is great, but what happens when you forget to label your chemicals? How do you know if you turned a clear glass of ammonia into a clear glass of unobtainium? Chemists have a tool for just that. Litmus paper are small bits of filter paper saturated with a reacti ...more

Keeping apples or avocados from browning after being cut is impossible; within minutes of being exposed to air, these fruits (yes, avocado is a fruit) begin to brown. No matter what you try—adding lemon juice, keeping the pits in place, immediately sealing the produce in an ai ...more

Glass is one of the least reactive substances known to chemistry. It is the standard container material for almost all lab chemicals because it's so inert. But there are a couple of substances that have strong reactions with glass. Sodium hydroxide, aka solid drain cleaner or ...more

Once you've reached an age where sparklers are no longer fun, it's time to upgrade to science and steel wool. It may be basic chemistry, but as you'll see in the video, simplicity can amaze more than complexity, as well as create some really impressive fireworks that are perfe ...more

Caramel is delicious, but it can be a tricky flavor to incorporate into baking. Traditionally, caramel is a liquid, and that doesn't always suit dessert preparation since adding extra liquid to baked goods can ruin them. So how do you get that buttery, toffee-like flavor? Ent ...more

Even the best-maintained kitchens occasionally get a fruit fly infestation. These critters descend, lay eggs (up to 500 at a time!), and then disappear usually only after extreme cleaning efforts (i.e., finally attacking that weird puddle of goo behind your refrigerator). And ...more

If you've ever turned on an episode of Iron Chef or Top Chef, chances are you've seen a contestant in gloves and goggles, yielding a canister that looks far more fit for a chemistry lab than for a kitchen. Wonder what's in the canister? Liquid nitrogen, the go-to tool/ingredie ...more

I finally got around to trying out another one of Will's mad science experiments and found out that this one was actually more satisfying (and less frustrating) than my slightly uncooperative jar jet. There's something very pleasing about making potassium nitrate at home in th ...more

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. The metallic form has limited uses in chemistry, and is too soft and reactive to be used as a buil ...more

The only thing better than successfully pulling off a new experiment is doing it with household materials. You get to laugh in conceit as professional scientists everywhere spend all their grant money on the same project you just accomplished with some under-the-sink chemicals ...more

In this video, I'll be demonstrating how anyone can make their own iodine clock reaction with simple over-the-counter chemicals. Video: . Household Materials Needed Hydrochloric acid (for cleaning purposes) Hydrogen peroxide (3%) Sodium hydroxide (drain cleaner) Povidone-iodi ...more

Staying inside during the coronavirus pandemic isn't easy for most of us. As important as it is to keep away from others, it can be challenging to keep to ourselves day after day. That's why mobile game developers are stepping in to help; many are making their games free for a ...more

If you want to convince your friends that money is not an issue, then you can just burn it for real like Walter White. But if you don't really want to destroy your hard-earned cash, this burn trick is perfect for you. It just takes some basic chemistry and a few materials, suc ...more

While the airline, casino, cruise, and hotel industries are asking for government bailouts during the COVID-19 pandemic, companies around the US are giving away its apps and services for a limited time. So while you're stuck at home, keep your mind off of coronavirus with free ...more

If you're a Breaking Bad junkie who can't wait for the next episode, satisfy your craving with a little at-home chemistry and make some blue DIY smash-glow crystals! No, this is not Walter White's so-called "Big Sky" or even the subpar cringe-worthy product of his competitors. ...more

Who could resist a gummy bear? Those rubbery little candy creatures shaped like a bear are just too cute and too delicious to pass up. If you can't get any enjoyment out of those gelatin-based confectioneries, then you're simple not human. Even scientists love them, but not fo ...more

There's a common saying that separates cooks from bakers: baking is a science, while cooking is an art. When baking, one little misstep can alter the texture, taste, and consistency of any recipe. Yet it doesn't have to be a scary science—forget your not-so-happy high school ...more

Whether you are just starting or returning to college, or have already been out in the real world for some time, it's always a good idea to stay on top of your game by keeping your intellect sharp. While it may be easy to just sit in front of your TV, watching reruns of The Bi ...more

Science is most marvelous when it's creating an explosion, even at the tiniest of proportions. In the video below, Daniel Rosenberg from Harvard's Natural Science Lecture Demonstration Services reveals the secret to shooting a cork rocket over twenty meters using a little chem ...more

If you want to appreciate the value of microbes, look no further than a chunk of cheese. Because cheese roughly traces back to the Neolithic Era, we might say the earliest cheesemakers were the first humans to manipulate microbes—without even knowing it. Now, thanks to microbi ...more

Impossible, right? Ahh, well science says fire and ice can and do coexist. The Science of this experiment:Dry ice at -109ºF, is frozen carbon dioxide (CO2), not water (H2O). Dry ice is also much colder than a freezer ice cube. To be exact it is almost as cold as Earth's cold ...more
