Here's something to look out for if you haven't found them yet. Inside the push button of the smaller size non-aerosol spray bottles there is often a wonderful semi-opaque 'wine bottle'. Trim 1/16-1/8" off the bottom, give it one coat of red glass stain part-way up the sides to represent wine, and finally cover the whole bottle with one coat of green or brown glass paint. The red will show through the green or brown but as the colours are transparent, it really looks like a glass bottle with contents. BTW, don't forget to salvage the washer, spring and clear tube for other uses.

Look for different shaped tabs on juice containers. Tropicana has an oval one.
