This program covers the very important topics known as atomic number, mass number, and isotopes. We begin by discussing the structure of the atom and how the atomic number is used to organize the periodic table. We discuss the mass...

The video is a lecture on titration calculations. The video is divided into two parts, with the first part focusing on concentration and molar concentration. The professor explains the concept of concentration and how it is calculated...

In this live-action program viewers will learn that scientific disciplines, such as Earth Science, Biology, Chemistry, and Physics, are based on observation and experiment. Students will come to understand that the first line of defense...

I spent some time on the football field teaching a group of kids how they can use Newton’s Second Law to improve their game.

NASA Goddard scientists have made an exciting discovery on Saturn's largest moon, Titan. The team has definitively detected the molecule acrylonitrile in Titan's atmosphere - a finding that has astrobiological relevance....

Have you ever wondered what happens when you bring a magnet near 5000 degree molten Iron? Does it attract? Or repel? Maybe it create cool shapes. But most importantly... DOES IT EXPLODE?!



I set off thermite over a very large...

Today im demonstrating the Synthesis of Benzocaine! <br/>
I used<br/> 150<br/>ml EtOH
15gm PABA
6ml Sulfuric acid

Pouring Molten Salt in Watermelons!

Its so easy to turn an old tv into an oscilloscope, I filmed this entire video in a few hours.

Pop Champagne with SCIENCE

How to generate chlorine gas with TCCA, HCl. Then how to condense it into a liquid with Dry Ice/Alcohol.

In this video we will explore the reaction between acids and metal carbonates. Recall that an acid is a chemical that contains a special type of hydrogen that can be released into aqueous solution as a hydrogen ion, H+. Most metal...

Learn the basics about bucky balls, graphene and nano tubes. This video start with a short recap on Allotropes and then starts you off learning about Fullerenes and Graphene and then gives you an overview into nanoscience and it's uses...

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

I made this pulse jet with a 1/2 scale because I couldn't find the correct size pipe for a full size.<b<br/>r/>

I'm using "rosscojector" style injection but it won't stay for more than 30 seconds. Unregulated

Hand grenades are small bombs that function like firecrackers. They are filled with gunpowder or explosive filler and a fuse. Hand grenades are activated via a mechanical device rather than requiring a person to light them with a match....

This live-action video program is about the word biosphere. The program is designed to reinforce and support a student's comprehension and retention of the word biosphere through use of video footage, photographs, diagrams and colorful,...

I couldn't find any info on any projects like this, so I thought I would have a try myself. I thought an oven would be the perfect platform, it already has a door, space for insulation, and comes with heating elements!...

Today I make a REAL hoverboard out of dry ice! It doesn't lift you high into the air like back to the future, but it perfectly emulates the feeling! Its just a wooden board with a rim around the edge to hole 3 blocks of dry-ice in place....

This is a lecture presentation on the electrolysis of aqueous solutions. The presenter explains what an aqueous solution is and what it contains, particularly aqueous solutions of metal salts. The presenter then presents a hypothesis on...

Imagine synthetic antibiotics that could fight infections like MRSA, custom pharmaceuticals to treat advanced prostate cancer, and new enzymes that will turn cellulose into fuel. With support from the National Science Foundation...

Usually Thermite is used to destroy things... Instead, I wanted to use it to make something to destroy things with.



If you have never heard of it -Thermite is a mixture of Iron Oxide (rust) and Aluminum powder. When you...

People were debating on how fast the ball was really spinning, and I had to find out for myself so I grabbed my camera that can shoot up to 1000fps. The original poster estimated the speed at 10,000 rpm, but the ball was really spinning...
