Latest post of the previous page:

I didn't get as hi-tech as a punch (although I do have a few); hammer and nail did the trick (the second time - the first time I overdid it and the battery shed the make-your-fingers-feel-soapy fluid, i.e. alkaline solution). You can also do it by putting the positive terminal onto the magnets; the negative is sufficiently large and uniform to allow a lot of leeway.

There are three fundamental questions for anyone advocating Brexit:

1. What, precisely, are the significant and tangible benefits of leaving the EU?
2. What damage to the UK and its citizens is an acceptable price to pay for those benefits?
3. Which ruling of the ECJ is most persuasive of the need to leave its jurisdiction?

Not quite a "science video" yet, but I've been doing a bit of filming with the Beeb. If all goes to plan and the Budget doesn't entirely take over, I'll be touting for astronomy (and trying not to make a parus major of myself) for a couple of minutes on South Today, tomorrow (18th Mar) sometime after 18:30. Apparently, some of the other material we filmed may make it onto their Facebook page.

+1 Steve!

I had not thought nor heard about the dust trajectories. I would guess that some clever sod could derive the gravity from the particle paths and known size range/density/mass (which they surely recorded?).

But then, if it was a spoof they would spoof that data as well I suppose. No, hang on . . . My brain hurts!

The dust trajectories were unfakeable with 1960/70s tech. See, for example, http://scholarlykitchen.sspnet.org/2013 ... o-fake-it/

Seem to remember a similar technique, though not so ambitious, on here before. May have been a concept or viability trial.

Seems the technique has been used in the Netherlands on the Coen Tunnel, 1283m (though not all covered) long built 1966.

But this is a brilliant idea and open to other uses (storage, experiments etc.)

Some impressive kit there. I liked the Bebop one in the other ads as well, very professional tool. But the ads change every visit . . .

So I found a review, though this does not show others things, such as VR:
