Frank Epperson was a question asker and an experimenter as a child, especially with flavoured soda waters. He tested a lot of his concoctions on his little brother Cray. One year there was a cold snap in California where the weather dropped below zero and he experimented with a glass of flavoured water and voila a frozen drink on a stick. Eventually he worked out how to produce them in volume and called them the Ep-sickle, and eventually the Pop-sicle.

Books About Inventions
Here are ten picture books written about inventions. Students could work in groups of three to read the book and research the inventors. The group then prepares a 3-part presentation, each student taking one part. They may choose any of the following responses:
- A poster “celebrating” the invention and the inventor
- A comparison of similarities and differences of the “Real Life” of the Inventor to the book’s version
- A set of imaginary entries in the diary of the inventor
- A humorous poem about the invention and the inventor

The Science of Liquids
There are three experiments in the book that are feasible for students.
- Why oil and liquids don’t mix
Oil is lighter and will float on water. If a drop of food colouring (which is water-based) is dropped into the oil, it will progress slowly down to reach and colour the water level.
- How to make your own lemon-flavoured soda water using baking soda.
The baking soda reacts to the acid of lemon to produce carbon dioxide.
- How salt lowers the freezing point of water.
