World Record 100 Balloons Popped By Laser [Video]

World Record 100 Balloons Popped By Laser [Video]

DO NOT TRY THIS.. What’s better than laser experiments?  Lasers popping balloons of course.  This home experimenter apparently holds a world record: Here is a world record submission video of 100 balloons falling like dominoes in a single file line. If confirmed, this will have been the most balloons in a single file line consecutively

Guy Makes Massive 40W Laser At Home [Video]

DO NOT TRY THIS.. The ever adventurous styropyro demonstrates a massive 40W laser that he made himself.  Do not try this without the supervision of a professional.  Here is how he describes it: I finally got a hold of a carbon dioxide laser, this one packing 40W of output power. This laser’s power puts the

Watch Melted Glass Conduct Electricity With A Homemade Lens

This home experimenter reminds us how much power comes from the sun.  He takes a video of a really cool lens he setup in his backyard: Using a large Fresnel Lens and concentrated sunlight solar, melted glass becomes electrically conductive ionic electrolytic conductor. Note: Do not try this without the supervision of a professional. Did you

Have You Ever Seen Dry Ice Bubbles? [Video]

Watch what happens when you touch them… Steve Spangler makes some really neat dry ice bubbles and here’s his instructions: Bubbles are cool, everyone knows that but bubbles filled with fog are even cooler! This amazing kit allows you to generate your own dry ice-filled bubbles, and bounce them in the palm of your hand.

Watch A CD Shatter At 170,000 Frames Per Second [Video]

I guess CDs are still good for something.. The Slo Mo guys have been making cool science videos and using special equipment to view reactions at extremely slow speeds. This helps us see some of the underlying scientific and physics effects in regards to different substances, objects and reactions. In this one they use a

They Put 1,500 Ping Pong Balls In Liquid Nitrogen [Video]

(note the demonstrator running away) What happens when you put 1,500 ping pong balls in liquid nitrogen?  These brave experimenters attempted this and filmed it!  Note do not try the experiment without the supervision of a professional. What do you think happened?  Liquid nitrogen is super cold so does the cool temperature make a vacuum

Food Coloring And Milk Experiment

Here is a really cool experiment that has a surprising outcome: The key to this experiment is the chemical reaction between the milk and the dish soap. Dish soap has molecules with properties that allow them to dissolve both water (a hydrophilic property) and dissolve in oil or fat (a hydrophobic property). The combination of

Guy Puts A Neodymium Magnet In Ferrofluid

The effects might surprise you. This stuff is bizarre and has only been around in the last 50 years. Ferrofluid was invented in 1962 by NASA.  It becomes extremely magnetized in the presence of a magnetic field.  So, this home experimenter shows what happens when you put a neodymium magnet in a bunch of this

What Happens When Neodymium Magnets Reach terminal Velocity?

Can you guess what happens?  This home experimenter displays the awesome power of neodymium magnets.  Here is what is being displayed: 4 Hexagon layers of Neodymium magnets reaching Terminal Velocity with the help of some compressed air. Hanging from a string of Neodymium magnets.  The magnets reach such a high speed the magnetic force can

Very Cool Domino Tricks That Will Amaze You

This video shows off some really cool domino tricks.  And, there is some interesting science and physics behind it: Mathematicians have traditionally assumed that no domino could knock over a neighboring domino more than about one-and-a-half-times its own width, height, and thickness, or a “growth factor” of 1.5. But there was no overarching mathematical model.

Top 10 Science Tricks Using Liquid [Video]

Everyone (or most people) appreciate a cool science experiment on video.  None may be more famous than the coke and mentos guys that went viral a couple years back.  In this video they show 10 really cool science experiments that use water.  Here is the first: 1. Slow motion ball: You need a thick liquid,

Hypnotic Water And Sound Experiment Part 2 [Video]

There is a famous video that made its round around the internet where a hose and water dispensing device had different sounds moving them.  The effects were awesome and this video is a part 2 to that experiment.  Here is what to expect: The effect that you are seeing can’t be seen with the naked

Water In A Zero Gravity Environment [Video]

Watch in amazement as NASA experiments with water in a zero gravity environment.  They do a few different tests including putting a bubble through this blob of H2O as well as a string.  There is even a challenge question near the end of the video if you are up for answering it.  Let’s see if

They Lit A Ping Pong Ball On Fire [Video]

You’ll be surprised at what happens… Do not try any of these without the supervision of a professional! (seriously)  Now that we have said that, there is not just the ping pong trick but actually 10 tricks in this video.  That just happens to be one of the cool ones.  Here is another that is
