Could I build a nuclear reactor based on Bernoulli's principle?

So I was recently inspired by the answers that I saw on this stack exchange to the following question: Feasibility of H.G. Wells' Continuously-Exploding Atomic Bombs

And it occurred to me that you can make the core as hot as you want, as long as it doesn't touch anything. So, envisioning ping pong balls hovering on hair dryers (via Bernoulli's principle), I was wondering if you could build a reactor where a mass of uranium is left hovering in a (fast-moving) column of coolant inside a larger tank. The motion of the liquid serves to cool the core, as well as keep it in place in the vessel. Incidentally, if you use many smaller uranium pellets in the core, and they are held together in this column by Bernoulli's principle, you might be able to stop the reaction by slowing down the coolant flow and letting them all fall down and separate.

So, is it possible to build a reactor based on these ideas?
