Science Projects And Inventions

YOU NEED:

• A piece of rubber tube
• A glass rode or piece of pipe
• Some masking tape
• Two bowls
• Some water

The Greek mathematician, Archimedes invented simple method to pump water to a higher level and this was widely in use in the days gone by.          

Try this. Wrap a rubber tube around a rod or a piece of pipe and then fasten it with tape as shown in illustration. Put the lower end of the pipe or rod in a bowl of water and keep rotating it. You will find the water travelling up the rubber tube and flowing out of the upper end into a basin or bowl held below it.

HOW DOES IT WORK?

Water flows into the lower part of each coil of the rubber tube wrapped around the rod of pipe. With the rotating motion, the water – bearing coils are pushed upwards and the water comes out at the top.
