If you’re up for a bit of scientific experimentation, you can get a McDonald’s hamburger, leave it on the counter, and prove to yourself it won’t appear to rot or decompose over time. Alternatively, you can skip the experiment and trust me on this, as a parent of a child […]
Why McDonald’s Hamburgers Don’t Decompose
A volume conversion can be difficult to understand if you try to grasp the problem all in one step. Many volume conversion problems give the student a series of linear distances with one set of units, but want the volume in a different set of units. At first glance, this […]
Cubic Feet to Liters Volume Conversion Example Problem
This wax and sand volcano is a realistic model volcano that is easy to make and erupts much like a real volcano. The volcano is extremely simple to make and interesting to watch. Wax “lava” forms a volcano in sand, eventually erupting into the atmosphere, which is water in this […]

What’s better than a regular Halloween jack o’ lantern? How about one that shoots out red fire? The red flames are easy to produce and last about an hour. They shoot up 2-3 feet into the air and range from orange to vivid red. Here’s how to do it: Red […]

The traditional version of the project produces flames, but here’s how to perform a safe version of the project. Safe Self-Carving Pumpkin Materials If you can get it, this project is […]

They can live for a week without a head, survive a month without food, and appear unaffected inside an operating microwave oven. While it’s true the insects can survive harsh environments, can they really live through the detonation of […]
Can Cockroaches Survive a Nuclear Bomb?
