In this video we make electric matches to safely detonate our experiments.

You should aim for a 95-5% ratio of your propellent to nitrocellulose (pingpong ba
l
ls).

A pingpong ball weighs 2g, so use about 50g of powder....

Scientists in China have successfully used gene editing and stem cell techniques to produce mice with two mothers.

The torch is self-igniting, meaning it has an electric sparker built in. When the button is pressed halfway, the torch mixes a perfect combination of propane and air into the tube. When the button is fully pressed the torch sparks...

I thought it would be fun to film propane balloons exploding in slow motion, and I tried popping them a bunch of different ways. I took some user suggestions like flying a drone with a sparkler attached into a balloon, and...

I made a freeze ray! Im basically a bonafide evil genius now. Freeze your cat, girlfriend, or flowers, the possibilities are endless..! wait no, thats about it.

Some notes about the
gun:
There are commercial liquid nitrogen...

My new foundry is made from:

Insulating fire
brick
High Temperat
ure mortar
Bio-Soluble
Ceramic Blanket
I highly recommend looking for a HWI distribution center near you. They sell to individuals, and because they...

Engineering Expo 2K16 (Science Show)

The video discusses how solutions to problems may not always be complete remedies and may only solve part of the problem. The video explains how scientists and engineers are still working on improving the solution of creating cleaner...

Is there life beyond Earth? How did life get started on Earth anyway? This season of NASA’s Gravity Assist podcast is about the origins of life on Earth and the search for life elsewhere.[scald=338003:full_width][scald=338003:full_width]

Molten Metal Squirtgun!

Underwater explosions using Dry Ice, and Liquid Nitrogen, and captured in high definition slow motion.



Hey guys, Backyard Scientist here. I this video I throw water bottles filled with dry ice, and liquid nitrogen...

The battle is on for the title of "America's Scientist Idol." Videotaped at the 2013 annual meeting of the American Association for the Advancement of Science, this "game show" pits six scientists against each other to see who can best...

Molten Aluminum Volcano

Most people have never heard of the Cerrejón coal mine, located in Colombia. The mine pumps out over 30 million tons of coal each year, and it's also become a critical site for scientists. In fact, the coal mine ranks as one of the best...

Today I put the Leidenfrost effect to the test! Im trying out a great question from somebody on my facebook page. He wanted to know if a hot object will fall faster than a cold object through water. I set up my fishtank and dropped...

The video discusses the process of designing solutions to problems in the fields of science, engineering, and medicine. It highlights the importance of gathering information through investigations, experiments, research, and data...

Ever wonder what would happen If you poured molten aluminum into a lava lamp? Me neither. Well, you voted, I listened! Some of my viewers on my Facebook, and G+ pages suggested that I pour molten aluminum into a Lava Lamp. That sounded...

You have probably heard of steel wool before. You can burn it and swing it around to create amazing sparks and effects. I thought it would be fun to attach steel wool to a drone and fly it around a beach at night. It turned our really...

Ok thats it, Fidget Spinner trend is over, cause this is the best one ever!! ;) I built a custom fidget spinner out of 1/4in aluminum plate and strapped 3 E sized rocket engines.



Really, I just wanted to do this. I saw...

I packed a fishtank completely full of water balls (water beads, water balz, orbeez, spitballs...). Im guessing there are over 10,000 in there!

The search for a mysterious subatomic particle can certainly involve some enormous tools, not to mention a multitude of scientists. The effort to find the elusive ""Higgs boson"" includes over 5,800 scientists from 56 countries! The...

Pouring Molten salt into Water - Explosion!

What happens when you fill a ping pong ball with extremely flammable propane, then light it on fire? Does it spin really fast, or make a cool noise, or explode? The answer is yes!



Last video, I made a mistake. I forgot to...

Using a 200w induction heater to heat a bolt, then dropping it into liquid nitrogen. The liquid nitrogen starts leaking and science quickly devolves into shenanigans :)
