A plastic bag is connected to a vacuum pump. Initially the air inside the bag pushes out with the same force as the air outside of the bag pushing in. However, when the air is pumped out of the bag there is nothing to counteract the atmosphere squeezing the bag against the bear.

Last time we saw that we can separate mixtures by using size and magnetism. This time we use density to separate a mixture. This process is used to separate different types of plastics so that they can be recycled.

River sand is a mixture: it’s a combination of many types and sizes of materials that are combined together without being chemically bonded to each other. Mixtures can be unmixed, or separated into component parts using various physics techniques.

On August 21, 2017 a total solar eclipse swept in a thin arc across the country, and a partial eclipse was viewable across almost the entire continental United States. This also happened to be the first day of the 2017-2018 academic year, and students all over Colorado State University took a break from their studies to watch this rare celestial event.

The Great American Solar Eclipse was a once-in-a-lifetime opportunity where a solar eclipse is visible from the entire continental United States. The Little Shop of Physics hosted several events surrounding the eclipse, which took place on the first day of the 2017-2018 school year. The main goal of all of the events was to use this unique opportunity, when much of the country was outside, looking up to the sky, to engage the public, to give people a chance to safely experience this remarkable celestial event.

More pixels means a more clear picture, but it also means that it takes longer to send the data from one computer to another. We use glass spheres to represent pixels. Increasing the bandwidth means moving more data (spheres) each second.
