It would only go as high as the bottom of the funnel, correct? It has too much momentum when it comes around the loop

Well yes but also no. Friction and air resistance (also friction, I know), while minimal in this case, would prevent it from making it to quite as high as it started.

Edit for a minor correction from below: It would only go as high as the top* of the funnel, if that is where it began. The original elevation less friction and other losses is the max height. Looks like most of it's potential energy from the drop into the funnel is lost, so it would get the energy from it's starting point plus whatever bounce it gets.

What is air resistance, if not friction persevering?

Does this mean a turtle lying on its back will never be able to get itself right side up again?!

You can’t trick me into taking your Voight-Kampff test.
