How To: Do a flaming ice experiment

In this fascinating "how to" video, you will see how a simple process creates the illusion of ice that is burning. Only a few items are needed to enact this scientific experiment. As the narrator describes, "Calcium carbide reacts with water to form acetylene gas." To illustrate, the video shows a bowl of ice cubes, to which the special ingredient is added. As the ice melts into water, it reacts with the calcium carbide, forming the high flammable acetylene gas, which is often used in welding...

It won first place for origami/nonprofessional. This plane flies excellently in a fast, long distance glide! Learn how to make the origami SST paper airplane by watching this ins...

News: Why Defining Steampunk Is Worthwhile

I've tried my hand in the past at defining Steampunk, but as anyone else who has made a similar attempt will tell you, there's a significant backlash from the community against working to create a real definition of what Steampunk is. That may sound ridiculous to some, but it's a very serious matter to others. With the recent announcement that TeslaCon 4 will be called the Congress of Steam, I think it's appropriate to talk about why all of this stuff is worth it. In this article, I'm going t...

How To: Calculate sums in standard form

How To: Determine the age of a fossil using carbon-14

If you have a fossil, you can tell how old it is by the carbon 14 dating method. This is a formula which helps you to date a fossil by its carbon. If a fossil contains 60% of its original carbon, how old is the fossil? The half life of carbon 14 is 5600 years. That means this is how long it takes for half the nuclei to decay. After 5600 years, if we start with a gram, we end up with half a gram. This rather complex formula shows you how to solve this puzzle using accepted scientific methods.

How To: Understand the secret behind vanishing tricks
