Here’s a neat thing: a formless gel that can be cast into a mold. When removed from said mold, it flows like a thick amorphous liquid. When immersed in water… it re-takes the form it had in the mold.

That’s *should* be pretty spiffy. But there are two issues, as I see it:

1) it’s  pink translucent goop that looks almost exactly like The Blob

2) What’s the gel made of? You got it… DNA.

Ummm.

DNA hydrogel has a long memory
