Ok I don't understand how this works but it happened. Boats fly...
Ok more like bounce but you get what I mean.

This is intended - boats are entities, and so, they bounce on slime blocks.
Yeah but not when they are perfectly still. You place a boat on a slime block, don't let it bounce, but just place it, and it'll still bounced up when you get in it. Yes boats do bounce when falling onto slime blocks, that is intended, but what isn't intended is boats bouncing into the air for no reason when getting into it. Watch the video in case you didn't.

You obviously didn't watch the video or at least all the way through.

Ok Ok Ok. It turns out you don't even need to do the piston thing over and over again. The boat will bounce really high and unless it falls back onto the slime blocks it'll bounce again at about the same height.
