    Double Dominos

    Double domino's are relatively hard to explain so you should watch the video to get a good idea of what it is. This is possible because the bricks are very wide. when the bricks fall, they lay on top of the one before it. the last brick in the sequence does not have anything to lay on so it falls to the floor. this causes the brick that is laying on it to fall as well and the next brick to fall and so on. This happens only when the bricks are placed a certain distance away from each other. this distance cant be too close or the bricks will just rest on top of each other. this d
  2. fiber optic cables are used to send messages at high speeds and at great distances. There exists a fiber optic cable traveling from New Jersey to England! fiber optic cables work by sending pulsing light through a specific material. since light is the fastest thing in the universe, fiber optic cables are the fastest form of communication in the known universe. as you know, light travels at different speeds when its inside of a different median. the ratio of the speed of light in air to the speed inside of the material is known as the index of refraction. a higher index of refraction means that

    Can Openers

    The tab on top of a soda can is more complicated than it may seem. First, the tab acts as a second class lever. a second class lever is a lever in which the fulcrum is at one end and the load is in the middle. the load is the point where the tab is attached to the can. In a second class lever, the force only moves up. One example of a second class lever is a wheelbarrow. The rivet in the middle of the can is pulled up until it reaches a point where a small crevice opens up. once this crevice appears, the tab immediately turns into a first class lever. a first class lever is when the fulcrum is

    I noticed a peculiar message on my package of noodles when making dinner the other night. It said something like "microwave on high (1.0kW) for 2 minutes". I was rather confused. I thought that all microwaves had the same cooking ability, but apparently not. The "1.0kW" section of the instructions indicated to the power of my microwave. The noodles required that I use 1000 watts of power for 2 minutes in order to cook properly. Electrical energy is calculated using E=P*t, and is measured in kilowatthours(kWh). The noodles only require an energy of .033kWh. My microwave has 1500 watts. That mea

    Recently I went to Altitude, a trampoline park. Trampolines make you jump really high. Trampolines are made of a woven material that is connected to springs on all sides. These springs are what give trampolines their ability to throw people in the air. Lets say that the trampolines at altitude can make me jump 2 meters high. That would mean I have a gravitational potential energy of 1245 joules at a height of 2 meters. All of that energy would be converted to elastic potential energy when I jump on the trampoline. 1245 joules of elastic potential energy means that the trampolines have a spring

    Coin Flips

    Does a coin have an equal chance to land on both sides? no actually. there is a 51% chance that your coin will land tails up compared to heads up. that is why tails never fails (only 49% of the time). This is because the head of the president on a coin is made of more material than the building or symbol on the tail side. There is a better chance that if you spin a coin on a table, it will land tails up. Certain coins can have an 80% chance that they will land tails side up. Keep this in mind next time you want to win a bet.
  7. I wonder if it requires more or less force to chew french fries dipped in ketchup
  8. You spelled future wrong in the title you should do the physics (or lack there of) in Doctor Strange.
  9. Linus Tech Tips is one of my favorite Youtube channels!!!
  10. This is interesting! Fluid mechanics is how hydraulic press's works.

    A guillotine is a medieval weapon used for public execution of prisoners. the way that a guillotine works is a blade attached to two parallel tracks drops onto a persons neck, displacing their head from their body. the blade of a guillotine has potential energy when it is at the top of the tracks. that potential energy is converted into kinetic energy when the blade is dropped. the blade is able to separate a human head from a body because it has a lot of energy. normally, guillotine blades are very heavy. this enables them to have a lot more gravitational potential energy because Ug=mgh. a mo
  12. I remember there used to be a Youtube channel dedicated to microwaving random objects.
  13. I wonder what would be an adequate test for strength if you are two completely different sized humans?
  14. We all know about inelastic and elastic collisions. inelastic collisions are when two or more objects stick together after contact. elastic collisions are when two or more objects bounce off each other after contact. what on earth is a superelastic collision then? first, an inelastic collision is when the kinetic energy before the collision is greater than the kinetic energy after. an elastic collision is when the kinetic energy before a collision equals the kinetic energy after the collision. therefore, a superelastic collision is when the kinetic energy before a collision is less than the ki

    The Dead Sea

    The Dead Sea is a lake that is bordering Jordan on the left and Israel on the right. The dead sea is special because it is the most extreme hyper-saline lakes in the world. a hyper-saline lake is a body of water that has high levels of sodium chloride. Hyper-saline lakes are saltier than the salt water that makes up our oceans. The dead sea is the most extreme meaning that it has the highest salt content of 33.7%. The salt water in the ocean only has a salt content of 3.5%. the dead sea got its name because of its high salt content. when people swim in it, their natural buoyancy enables them t
