What we’re seeing here is a whole lotta things: We have diffuse reflection all over the place, we have direct transmission (both through the clear plastic bottle and through the clear glue), which gives us refraction, we have diffuse transmission… you name it. The only thing I’m pretty sure we don’t have here is direct reflection, since as far as I can see there’s no way to get direct reflection (the angles don’t work).

Not bad, huh? Next up, some killer tomatoes ;-)
