A variety of activities performed at a science camp that relate to the chemistry of the solar system are reported. These activities could prove useful in the chemistry curriculum or in planning for National Chemistry Week in 2018, the theme of which is Chemistry is Out of This World!
Simple methods to prepare liquid air are described. In addition, ways to test the properties of liquid air and other liquefied gases are explored.
