This week, we have a special video from our visiting science teacher Chris Chiaverina. Chris shows us how a microphone works and how to build “Slinky Sounds”, an awesome little experiment that makes some sci-fi sound effects!

The Little Shop of Physics Open House takes place every year on the last Saturday of February at the CSU Lory Student Center. This free public event always draws a crowd, and this year is was no exception. Over the course of the day, approximately 10,000 people came to do science with us!

The Little Shop of Physics crew spent the first two weeks of 2018 doing what we love: sharing fun, hands-on science education, making new friends, having epic adventures, and trying not to get our solar hot air balloons stuck in acacia trees. Little Shop teamed up with B2Gold for a road trip to Namibia over CSU’s winter break, and we came back with lots of ideas and some great stories to share with you!

Eva has an egg and a bottle. The egg will not fit in the mouth of the bottle. She uses two different methods to get atmospheric pressure to push the egg into the bottle. The first method uses hot water, some of which evaporates. The water vapor displaces the air inside of the bottle. When the bottle is cooled, the vapor condenses into a liquid, which decreases the pressure inside of the bottle. The second method is similar, but uses a small fire to heat the air inside of the bottle, causing the air to expand. When the flame goes out, the air cools, lowering the pressure on the inside of the bottle.

As part of the Great American Eclipse, the Little Shop of Physics along with ESMEI handed out 50,000 pairs of glasses in order for folks to safely view the sun. The majority of these glasses were provided free of charge to K-12 and college students, and the remainder were given away. $5,000 in donations were collected for Robert’s Orphanage in Uganda.
