1. Does light really reflect off of Elmo and the Men? They aren't shiny and reflective like a mirror is, but we know there has to be light in order to see (that's what the dark room helped us really nail down).
2. We get that light must reflect off the mirror and transmit through it, but that's super odd how it can do both.
We were thinking that it would be great if we could get quantitative data to support this. Numbers don't lie, so we'd like proof that light reflects off of Elmo and the men, as well as numeric proof that light can reflect off of and transmit through a one-way mirror. If we can measure length, weight, and even sound, can't we measure light, too?
