Get Your Science On: Egg in a Bottle
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.
Eclipse Glasses Fundraiser for Robert Surenjogi’s Orphanage
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.
