I like exploring different ways of using chemicals. One method I have found that works for me and that I enjoy is transdermal administration of caffeine (through the skin). These caffeine patches give a more controlled release throughout the day and make the experience smoother, plus all I do is slap on a patch and forget about it.
This instructable will show you an alternative to the traditional method of ingesting caffeine from coffee: caffeine patches!
Step 1: Materials (Inexpensive)
-Large Bandages (small ones work too but are less effective, found at your local pharmacy for ~4 dollars)
-Pure Caffeine/Caffeine Pills (found online or at local pharmacy. I bought 1/2 pound pure caffeine online for ~4 dollars)
-A caffeine addiction
Step 2: -Measure Out Your Caffeine-
(I used 800mg for visual purposes.)
Step 3: -Dissolve Your Caffeine in Water/Alcohol-
You can also use alcohol (ethanol). The higher the purity the better.
Step 4: -Microwave Your Caffeine Water-
Now microwave your caffeine until the water is hot. One minute is a good universal setting since you are only microwaving a small amount. After microwaving, swish around your solution to ensure that all the caffeine has dissolved in the water.
The reason you are microwaving the solution is because caffeine's solubility in water increases with temperature. This concentrates more caffeine in less water and will make your patches more potent when you put the solution on the bandage. If you are using pills, this also helps to get more of the caffeine in the water and less of the binders/fillers in the pill.
Step 5: -Place Your Solution Onto the Bandage-
Once it is dry, your addiction-feeding patch is ready.
Note: If you wait too long and your caffeine solution starts to cool, the extra caffeine which dissolved will start to recrystallize aka turn back into solid caffeine. If this happens, simply re-microwave.
Step 6: Apply Liberally
You can apply this anywhere, I place it on my arm because I can. It is important to note that the thicker the area of skin, the less likely it is to absorb so don't place it at the bottom of your foot.
Using the patch immediately after preparing (while still wet) will significantly increase the effective absorption of the caffeine through the skin. Alcohol has better skin permeability (ability to move through the skin) than water and will maximize efficiency of your patches.
Enjoy your jitters!
