What happens if I point the laser into my eyes or someone elses eyes?

The light from the laser may cause temporary or in prolonged cases permanent blindness due to retinal damage.

At 1:11, it says to use 50 cm lengths of pipe, but would it work with shorter lengths of pipe?

of course you can improvise! this is SCIENCE!

would this work with a green laser?

It should work he was using a red laser because, probably it is more visible.

Would a chunk of CD be a decent substitute for the mirror piece?

CD's can shatter vigorously when broken, use caution and/or more protective paper/gloves.

Can this be made out of pipes other than PVC? It's not exactly the safest plastic around.

  I don't think so, it would probably not be bright enough or small enough.
