I need some ideas for a project. I need a few household items that would stop uv waves.

Thank you.

    Do they have to pass visible light? Do they have to be transparent? Almost anything that visible light can't pass through will also block uv light. There are a few exceptions, like black light filters (cobalt and nickel sulfate)

    he just said stuff like sunglasses, sunblock, but I wanted to try and get something better than that.
    Thank you

    It is easy to come up with a list of mterials to test, but you will need a device called a UV-visible spectrophotometer to measure the blocking effectiveness as a function of wavelength. These typically cost thousands of dollars. Will your school be providing such a device?

    Thank you for your help we did our experiment earlier today, it was not a big deal, just wanted something that nobody else had.
