There’s a test that can tell you if you unconsciously have negative bias towards a race or group of people!


The Implicit Association Test (IAT) is a new method of testing. It converges our conscious and unconscious minds better than any other previous tests. The thing is, we don’t always speak our minds, but we also don’t always know our minds. In other words, we don’t realize how we really feel or think about something always. Scientific psychologists developed IAT to understand this divergence.

The way most of the tests work is they present you with two choices. You're supposed to decide between one or the other very quickly. The tests mix and match different choices so that you tend to make decisions based more on your subconscious. Go take a test and tell us what you thought in the comments!

Being bilingual makes you smarter!


We've talked before about how learning another language can help fight dementia. However, it seems that there are more benefits than that. New evidence suggests that being bilingual can actually modify your brain in a way that makes you smarter!

This is in contrast to the view for most of the 20th century, when it was considered a problem for kids. People used to think that learning another language interfered with the academic and intellectual development.

There is some interference. Apparently, in a bilingual's brain, both languages are active at ALL times. However, instead of hurting and interfering with the brain, it helps it! It forces the brain to resolve internal conflict. 

Studies done with mono- or bilingual kids had them doing different cognitive tasks. In some tests, they performed at the same level. In other, bilinguals completed the task faster.

Scientists believe that the main benefit of bilinguals is that they are forced to monitor the environment at a higher level. For example, having to speak to your mom or dad in different languages keeps you on your toes and keeping track of changes.

In the 60s, A doctor in Canada treated some mental patients by putting a bunch of them in a windowless room together for days, naked and tripping on acid.


Oh Canada! In 1968, a doctor called Elliot Barker, head of the Oak Ridge Psychiatric facility began an experimental treatment. He created a unit called “Total Encounter Capsule.” 

Here's how it works. The capsule was a windowless 8x10 foot room with a sink and toilet that was soundproof and had a one way mirror in the ceiling. Patients were fed through straws in the door. The reason they were naked is because Dr. Barker thought that patients would be more inclined to reveal their inner selves if they didn't have any clothes. To make it even easier, he gave them LSD-25, to encourage communication. 

Entering the Capsule was completely voluntary, though, and each patient chose how long they would stay in the room. They stayed for a period of between 1 and 11 days. Night and day were indistinguishable, because the room was lit at all times. Not just that, the people running the room, keeping records, watching them over and maintaining proper room temperature, were patients themselves!

Some awesome lists!

You can measure the speed of light by using a bunch of marshmallows and a microwave!


Place one layer of marshmallows in a casserole dish. The dish should be completely covered in marshmallows. Put the dish in the microwave without a turntable and cook on low heat. Continue heating the marshmallows until the layer starts to melt in 4 or 5 different places. Microwaves do not cook evenly, so you have to allow for several places to begin melting.

Take the dish out of the microwave and observe the melted spots. Use a ruler to measure the distance between the melted marshmallows. Check the back of the microwave for its frequency. There will be a consistent distance between the melted spots of marshmallow and this distance is half the wavelength of the microwave. Finally, all you have to do is multiply the microwave frequency by the wavelength. The product is the speed of light!

There’s a lake in Indonesia that has the same pH value as car battery acid!


The Kawah Ijen Lake is located in a crater. The lake is the largest sulfuric acid lake in the world. The actual pH level in the lake is 0.5! As soon as you put an aluminum can in the acid it begins to sizzle and bubble. Within 20 minutes the material is eaten away to the point of it being as thin as tissue.

Despite the dangerous situation, there are people who actually work here. The crater happens to be a sulfur mine. Miners collect and carry huge loads of pure sulfur up from the crater floor.

The miners receive roughly $10 a day for their work in the hazardous environment. Clouds of sulfur dioxide gas are all over the area, and it's considered one of the most dangerous places in the world to work in.
