Messing around with some homemade lights

So I read a tutorial on DIY lighting techniques on my friend Dustin's website askthephotographer.com and it was an incredible cheap and easy setup. I went to the local hardware store bought 2 clamp dish lights, clamped them onto my kitchen counter, then made a little studio and put 4 white peices of paper and cornered them. Then got a glass of water and dropped in a lime and there you go. The glass wasen't perfect for this experiment but it's cool. if anyone wants more information on how I did this let me know.
