Glass Cutting and Etching...?

So, my History teacher sells Starbucks Frappuccinos for 2 bucks and I started asking my friend for her empty bottles. This is what I have so far.

8 bottles perfect for cutting and glass etching!
These are my materials, I spent like 30 or 40 bucks at Michael's (give or take, I bought some other stuff too) cost me like 8 weeks of allowance....

That's my bathroom rig by the way... Crazy right?! So little for so much! Well, I'm off to get the labels off the bottles! I found out oil (of any kind) and hot water and a rag do the trick nicely!
