In my show the Evaporation gimmick that I use in a milk bottle. Really it’s a Sunny D bottle that has a milk label that I printed out on it. Recently while I was performing in Wyoming I found this milk bottle:

This is my dream bottle for a milk bottle for my Evaporation trick. The only problem is that it’s a unicorn. What makes this bottle perfect for milk is that it’s smooth, which makes it easy to clean and it’s clear, so the liquid is very visible. Unfortunately I’ve spend too much time trying to track down more of these bottles and all the ones I can find are frosted and not clear. With a frosted bottle it’s hard to see the liquid inside.
Normally milk is in a frosted or opaque bottle as light isn’t good for milk. That convinces me that these were an error at the place that makes the bottles. Unfortunately I won’t be able to offer these for sale to magicians as there’s only two and I’m going to be using them. However if you want my standard Evaporation that’s gimmicked for milk, shoot me a note and I can make you one.
