Step 1: Turn the tap on, make sure it’s at your favourite temperature (i burned my face on the first few goes, but we all learn by practice!).
Step 3: put your mouth directly underneath the flow of water. Aim is essential here, or you might get a wet face – and that is yucky!
Step 5: fill your mouth up with water and then swallow it.
Step 7: repeat until quenched.
Step 9: and now you can use your redundant glass for bee-keeping or for your special university pencils and rulers.
