Laser Awesomeness…One of the world’s most powerful handheld lasers

Laser Awesomeness…One of the world’s most powerful handheld lasers

It’s no secret that we like to post fun laser videos, from homemade lightsabers to remote control robots equipped with attached lasers and the like.  Here is another video and this home experimenter boasts one of the most powerful lasers anywhere outside of a lab.  Here is an intro from the narrator: Designed with short

Fun experiment with fluorescent substance (fluorescein)

This is just a fun video that observes one of the neatest substances, fluorescein as it has very powerful glowing effects.  For those who don’t know it is actually the same substance that is in fluorescent/highlughter markers.  It is also used in military missions as well as in some other applications that might surprise you.

How to Create a Resonance Water Fuel Cell

This is a cool video showing a home experiment displaying some of Stanley Meyer’s principles with a water fuel cell.  Here is a bit more background on what is happening: Steps to achieve resonance: 1. Low Frequency (LF) “Gated” Generator is OFF. 2. Adjusting High Frequency (HF) Generator to reach a state of resonance. 3.

Guy Makes Hydrogen With Magnets From Home

Ok this is pretty neat!  This guy makes hydrogen at home and here is a quick description by the experimenter in this video: “making hydrogen with magnetic resonance (magnets) also taking steps toward a hydrogen cell that runs on tap water only no added electrolyte!” That is awesome because the world seems to be getting

Guy Makes a Vortex Canon That Shoots Crazy Air!

This is just a plain cool experiment although do not try this at home, indoors or without the supervision of a professional.  These guys show us how a vortex canon can actually shoot and knock things down.  In transcribing from the video the experimenter states: According to legend a really good blast of air should

Cool Home Experiment With a Floating Gyroscope

Here is a pretty cool science experiment with a levitating gyroscope.  It is based on something called lenz’s law and here is an excerpt on it from wikipedia Lenz’s law /ˈlɛnts/ is a common way of understanding how electromagnetic circuits obey Newton’s third law and the conservation of energy.[1] Lenz’s law is named after Heinrich

Guy Makes a Lego Tank with WiFi Powered by Arduino

Ok what’s cooler than legos and tanks?  How about a wifi controlled lego tank made at home and controlled by arduino!  The maker has a brief description here: A Lego tank that is controlled over Wi-Fi with an #arduinoAtHeart. Features include full remote control, automatic and manual front head-light control, 12+ shot rubber-band guns, full

He Made A Gyroscope In His Shop That Does THIS

Who knew a gyroscope can do THIS? This inventor and machinist makes a precision gyroscope in his maker space.  Many home enthusiasts and science fans know a gyroscope exhibits magical properties in that it seems to float when it spins.  You can see these effects all over the world.  Here is his intro to this

Flame Gulping Engine This is Just Cool

If you think a flame gulping engine is pure awesomeness than this is the device for you. This is a brief intro from the experimenter on what he has made: This is a video of the flame gulper engine pictured on the “Models” page of the Engineman website. The fuel is alcohol. It was made

Magnets Floating on Magnets Hover Like Back to the Future II

In this video the experimenter demonstrates a very cool magnetic effect.  It is called dimagnetism and that effect has incredible potential in future applications from hoverboard technologies to hyperloop style transportation and more.  For example, a superconductor could be considered a perfect diamagnet.  And of course neodymium, the elemental magnets that are incredibly powerful seem

Efficient Hydro Generator Made at Home

Ok this is pretty cool.  This home inventor makes a vertical turbine hydro generator system using a stream in his backyard.  Mark from this video was also seen on the television show “America Unplugged”.  He takes us to his barn to show us more of the components he used and information on how to construct a

Really Cool Small Cubes That Self Assemble

The team at MIT does it again with advancements in robotics.  In this video they demonstrate modular robots that change their geometry according to the task.  Its awesome because most robots are designed for a specific task and they have a fixed architecture.  They will perform that single task well but not be able to

Guy Makes RFID Garage Door Opener Using Arduino

If you’re an arduino fan or just learning, or havent’t heard about it here is a breakdown.  Arduino is an open source microcontroller that you can program to do amazing things.  Their boards are inexpensive and have a wide array of configurations such as the Ethernet Shield, Yun, Leonardo, Wifi Shield and more.  The basic

Bending a Laser With a Stream of Water

This is a cool experiment where the scientist bends a laser with a stream of water.  Note its a green laser for all you Star Wars fans :).  All our life we’ve been told that light travels in straight lines.  It can also appear to bend under the right conditions and they show you how
