Tried the straw trick with a Q-tip and it worked ok, just a bit underpowered. Ordered a couple frothers from China on eBay, $3 for both. Went ahead and got 2 in case one craps out. It works great. Goodbye incessant shaking!!! Used the frother and crock pot on my last batch and it's a vast improvement. Mixed in shot glasses (no beakers yet),
threw 'em in the crock pot and covered with a splatter screen, frothing for a couple minutes every hour. Gonna do up a batch tomorrow and test with/without the crock pot. Definitely think a frother should be just as much a part of the toolbox as a scale.
