I have one of these on my desk. It’s a little plastic container filled with mostly water, a blue colored liquid that’s a lot like oil (maybe it’s oil), and some air. You turn it upside down and the air goes up and the blue oil falls down like a Rube Goldberg device, turning a little wheel. The air goes up a little inclined path that looks like the first level of Donkey Kong. You turn it back around and the same thing happens, only the air goes up and turns the wheel and the blue oil falls down the incline.
Is there a general name for these kinds of toys?
Actually I just realized that since oil is lighter than water, it wouldn’t fall down. Let’s just say it’s a blue liquid then
If you could just discover how it got there, you might be able to unravel the mystery of its name. Did it arrive in the night? Or during your lunch hour? The people who have offered it to you: Have they made themselves known at all? They very well could have the answer.
