Make your own camera.
What you'll need:
- Pringles tube
- Metal tape (known as 'ThermaWrap' and available from most DIY
stores, or if you're a bit tight for cash, foil and a glue stick
can be used)
- Tracing paper
- Empty pot noodle (optional)
Follow these steps
- Knock a hole in the metal end of the pringles tube. Do this
using a large nail and hammer. Open the hole up until it's 1-2
centimetres in diameter. Or you could ask someone in your school's
DT department to cut a hole using a large scale hole borer and
pillar drill (this will give you a neater hole).
- Take a few centimetres of the metal tape and stick it across
the hole.
- Tape a tracing paper screen over the other end of the
tube.
- Make a tiny hole using an optical pin or the sharp end of a
drawing compass in the foil.
- Point the pinhole end at a bright object. Candles are excellent
if you have a good black out.
For better results, the length of the tube can be adjusted. For
ease of image finding, cut the tube to about 20cms.
A Pot Noodle also has its benefits for this kind of thing too.
Make a hole in the bottom end using a heated large nail. Take care
when heating the nail on a Bunsen burner. This hole also needs to
be about 1-2cms in diameter. And there you have it a
Potnoodlescope!
