I got my new AluBottle recently. The capacity is more than 1 liter, I think. This thing is huge. So I tried the following experiment. Instead of using an AluBall, I took a Fijian style strainer bag, from the late Luna Kava. This is a colorful cloth bag made from some kind of fine fabric, of the type that might be called kalico in Bislama. I place 1/2 cup of Kadavu Waka in the bag and tied it off with Montana grown dental floss, added 750 mL of water, and shook for about 10 minutes.
The thing is, 750 mL of water is really heavy, 1.65 pounds to be exact, plus the weight of the alubottle itself probably adds up to about 1 kg, so I actually feel like I got a little workout after shaking this thing. My resting pulse is about 60, but after shaking a fully loaded AluBottle for 2 minutes, my pulse had shot up to about 80-90.
I also felt like the Jolly Green Giant's fluffer, which was a little weird...
Anyway, aside from elevating my pulse and arousing some awkward feelings, the resulting grog is quite potent, so I'm calling this experiment a success...
