A few days ago there was a post on the Soylent Discourse forum about using a popcorn butter pump for oil.
The one linked was far larger than I would like and is designed for gallon size containers. I wanted one that would hold a few days (or weeks) of oil and would be practical on my desk at work (and another at home). Last night I kicked around Wal-Mart and found what I was looking for. Oddly enough the dispensers I’ve found are marketed as lotion dispensers.
This is the one I found. They were $1.88 each and hold 11 fluid ounces or 325ml – that should last almost 6 days with my current recipe. I wanted one that was see-through so I could monitor the oil level. I’m considering the possibility of adding them as an add-in for the mixed up People Chow I sell simply because it makes measuring so much easier and there’s enough room in the boxes for the pump.
If you are concerned about weird stuff in the plastic getting into the oil you could go with something with glass and stainless steel like this or just search for “glass lotion dispenser” on Amazon. I decided to put it onto a plate to make sure I didn’t lose any onto the counter while I filled it up.
Bottle full. It was actually really easy to fill. I thought I was going to need a funnel since the oil bottle has a massive opening and the dispenser is tiny but it went in without a spill…
… on the first bottle. On the second bottle I learned a valuable lesson I would like to pass on: DO NOT fill up the bottle close to all-the-way. Leave a solid inch or more at the top or when you put the pump in it will displace liquid and you will have a mess. I could tell this was about to happen so I tried to draw some oil into the pump as I put it in the bottle but the effort failed (as shown above).
Measuring how many pumps I needed to get my oil right was a simple affair. I’m measuring mine by volume so I just saw how many full pumps it took to fill up the appropriate measuring spoon(s). If you are measuring your oil by weight, you would just zero out a container on your scale and pump oil until you hit the right weight.
Measuring like this has the added benefit of running some oil through the mechanism to get out any possible residue left over from manufacturing.
After measuring mine I determined that with the specific pumps I have, I need 11 pumps to get the 3.5 teaspoons of oil necessary for each of the 4 “meals” of regular People Chow I’m currently consuming. It took all of 2 seconds to come up with a way to remember that.
And for an added bonus: I’m still laughing at the thought that someone might mistake it for hand soap and try to wash their hands with it.
Insert Dr. Horrible evil laugh here.
