Does anybody have any suggestions for something to use as an LED diffuser?

Needs to be bigger than a ping pong ball (ideally would be around 3-4 times the size) , but still be v.cheap and light.... as I have a lot of individual leds to diffuse for a display... cheers.

Just poke the led through the lid. simple.

Plain ordinary grease proof paper or tracing paper. or even the ping pong ball cut in half. you may b able to find small plastic shot glasses that you can frost with abrasive paper. (sand paper) use a very fine grade.

that's something i hadn't thought of! this project is outside so will need to be something able to withstand the elements for a few days

Scrunched plastic? Wouldn't look that good in daylight though. L

Prob a little tricky... am dealing with a lot of leds. Someone suggested disposable plastic espresso cups which could work well

Expanded polystyrene foam is another, but it can be rather messy to shape. L

How about using glass jars! ... you can then use a frosted glass aerosol spray to diffuse the light?

nice idea! although a little too heavy for this project, could use plastic tubs or bottles instead I guess
finely shredded newspaper?
