So, I've got to give you "cake & ice cream" which it seems hard to imagine how you could float just on weight grounds (though presumably you could use two spinnerets to create invisible "rails" and suspend something light enough on a paper plate). But some of the criticisms there sound—with no snark intended—more like failure of imagination than deceptive marketing. Yes, if you LITERALLY want to perform nude, you probably have to use the method that causes the spinneret to disintegrate, but for gigs where you happen to be wearing a button-down shirt or a belt, it's not rocket science to think of alternate handlings that don't have that drawback. (Which is how I prefer to use them anyway for other reasons.) Yes, the video doesn't walk you through floating foods other than strawberries, but surely you can generalize from that example and quickly prepare an item on the table wherever you're performing? (Again, admittedly easier if you're not actually nude & can cop something to prep in a pocket.) We're maybe not talking literally instantaneous impromptu performance, but with a bit of practice I think most of these setups could be done quite rapidly and surreptitiously, with the benefit that you can plant the spinneret (and maybe spin a thread), leave it, and come back to the prepped object after interacting clean with spectators (which for obvious reasons you probably don't want to attempt with your ITR).

For the cigarette float, here's an alternative I came up with that lets you use a borrowed pack: Just take some cigarette rolling paper and some double sided scotch tape & make a tiny packet of cigarette paper that's sticky on one side, and use that with a spinneret. Voila, now you can attach it externally to a borrowed smoke in a way that's pretty much invisible if the spectator's more than a few inches away.

I'll agree that in most settings you'd probably be better off just using, say, a Spider Pen—but there are contexts in which I think spinnerets have distinct advantages (like the ability to spin multiple "webs" that the performer can temporarily walk away from) if you're willing to apply a little ingenuity. I certainly wouldn't have minded a longer instructional video with some more routines, but most of this seems like stuff performers can be trusted to work out for themselves based on what is taught.
