Cognitive Surplus has released a number of new mugs aimed at teaching you about the sciences while you attempt to wake yourself up with morning caffeine.

Included are mugs emblazoned with astronomy star charts, lunar phases and vintage electromagnetism illustrations – including diagrams of Tesla’s inventions and foundational electrodynamics equations.

Each offering is individually boxed, dishwasher and microwave safe and capable of handling 11oz of your coffee of choice. Added benefits may include looking smart and engaging with fellow science nerds. Check out more examples below. [click to continue…]

I’ve said it before and I’ll say it again, the perfect time to contemplate the inner workings of the human body is during a meal. I mean, you’re experiencing digestion at that very moment! You can follow along with the digestion plate, or mix things up with the plates for the nervous, skeletal and muscular systems. Who’s hungry?

If you visit the Hoover Dam and are in the mood for a simple science experiment, grab a bottle of water and try to pour it over the dam. You’ll find that the super strong draft generated by the structure causes the stream to flow upwards, as revealed in the video below. Fun! [click to continue…]

In the following video Canadian YouTuber AvE demonstrates that Wonder Bread can be transformed into carbon foam – a substance that is said to be similar to the material used to cover the space shuttle.

The process is reportedly the same as making charcoal, and involves putting the bread in a very hot, oxygen-free container until it is blackened. The bread’s tiny holes are retained in the final product, resulting in a type of foam with “incredible insulating properties”.

AvE states that the substance has an exceptionally high electric resistance and can withstand temps of up to 6,600 degrees Celsius (or about 11,900 degrees Fahrenheit) without melting or burning. Instead, it sublimates, or instantly turns into gas.

Scientists working on a recent study for ACS Applied Materials and Interfaces discovered that carbon foam made from bread “is mechanically stiff, can shield against electromagnetic interference and is much less flammable than current carbon foams.”

In other words, this is a cheap and effective way to make a supremely useful material. See how it’s done in the video below. [click to continue…]

In her latest video, “Physics Girl” Dianna Cowern harnesses the power of electromagnets to obliterate soda cans.

The experiment was carried out with the aid of Arc Attack Studios in Austin, TX and utilizes an electric current running through a magnetic field. The power of the field increases as more current is applied, which in turn creates a secondary current with its own magnetic field that is aligned with the first. The resulting repelling force of these two fields leads to the can being violently torn apart.

Even if you don’t follow the physics, the video is still interesting to watch. Check it out below. [click to continue…]

Periodic Videos has transformed the Jagerbomb from booze into a bomb by adding sodium and potassium into the mix.

The sodium provides a pop and bright colors when it is dropped into the Jager and Red Bull concoction, while potassium causes a violent reaction that actually shatters the beaker.

While this is just a basic description, the video below provides all the details… and the explosions.

Geek store Cognitive Surplus has created a line of glassware for chemistry buffs that feature the molecular makeup of the beverages they’re designed hold. The line includes glasses suited to water, coffee, beer, wine and whiskey.

Besides being educational, the glasses are reportedly printed with eco-friendly ceramic ink for a raised rough texture. The ink also fires on at temperatures of up to 1,200°F and becomes part of the finish, so the image won’t peel, flake, or scratch.

YouTuber “Reactions” has turned your morning cup of coffee into a chemistry lesson, describing the science behind the perfect cup.

As you’ll see in the video below, the journey follows the coffee bean from the tree, through the roasting process all the way to the cup. You’ll also learn why coffee smells so great and the secret to freshness. However, the video moves pretty fast, so you may want to drink a cup before watching so you’re fully alert.

Using a fire extinguisher and science, Food Network host Alton Brown has demonstrated how a gallon of carbonated ice cream can be created in 10 seconds flat.

The aptly-named “Jet Cream” consists of three water cooler bottles duct taped together with the fire extinguisher positioned at one end. Pressurized liquid ice cream sprays into the device, where it is subjected to the Joule-Thomson effect as it is exposed to the extinguisher’s extremely cold CO2. This causes the ice cream to freeze almost instantly—while also being carbonated.

Head on over to Pop Sci to check out the video.

salt explosion

The Backyard Scientist has recreated a molten salt experiment in an attempt to figure out why it gets all explody when poured into water.

The slow motion footage is a sight to behold, but his theory about what’s happening is only one of many that are bouncing around the Internet right now.

Check out the video below and weigh in.
