Preparing Ethyl Ether:
WARNING: Ethyl Ether is very flammable and is heavier than air. Do not use ethyl ether near flame or non-sparkless motors. It is also an anaesthetic and can cause respiratory collapse if you inhale too much.
Take the unmarked small bottle and spray starter fluid in it until it looks half-full. Then fill the rest of the way with water, cap the bottle and shake for 5 minutes. Let it sit for a minute or two, and tap the side to try and separate the clear upper layer. Then, draw off the top (ether) layer with the eyedropper, and throw away the lower (water) and cloudy layer. Place the ether in the marked container. Repeat this until you have about 1.5 oz. of ether. Put the cap on it, and put it in the freezer if you can. Rinse the other bottle and let it stand.
Ethyl ether is very pungent. Even a small evaporated amount is quite noticeable.
Ephedrine & or P-Ephedrine: Please discuss this on the neonjoint forum
Three small glass bottles with lids (approx. 3 oz., but not important)one should be marked at 1.5oz, use tape on the outside to mark it (you might want to label it as ether). One should be clear (and it can't be the marked one).
A Pyrex dish (the meatloaf one is suggested)
A glass quart jar
Sharp scissors
Clean rubber gloves
Coffee filters
