Need a couple of topics for informative speeches

Hi,
I need a couple of topics for informative speeches. I'm supposed to have 5 topic prososals by tomorrow. The topics should be 'how to' speeches and they should be technical. So far I have only 1 which is "how to use filtration, chlorination to clean water in the house".
Other topics already taken by other students in the class include:
"How to assemble a PC", "how to fix a flat tyre".
So I still need 4 topics urgently, please...

Hi,

Try some 'How to' topics.

hi,
Thanks for the suggestions. But what I'm looking for is something more technical. Maybe something scientific or enginering related but still intersting.

We have a number of topics on the main Presentation Magazine site
