Can anyone lend us an underwater drill?

Nothing to report as yet on this one.

But does anyone remember a demonstration on TV donkeys years ago (1980s?) where a mains electric drill had some magic spray applied then was lowered into a fish tank whilst running? It might have been on the "Tomorrow's World" programme. Just wondering whether this hydrophobic spray may be useful for cordless drills in wet situations. Is it still available? Anyone know a trade name for this sort of product?

(BTW, we've no plans to try a mains drill in a sump, obviously!)
Now that you mention it I remember that.

Here's something similar but not the original that I remember
