The world's tallest aqueduct is near Llangollen, and stands at 126ft tall:
You can canoe over it - and this is what it looks like:

Reading a book about the extremes in nature/physics etc. The one on loudness is interesting. The French Horn is the loudest unamplified instrument, and a third of players under 40 have some related hearing loss. Something like Saturn V taking off is around 200dB, whereas Krakatoa or Tunguska were reckoned to be between 300-315dB*. Above 160dB at close range is apparently 'probably not survivable'.
*Being near anything like this would not only blow your eardrums, but also pulverise organs and shatter bones.

I read somewhere, a very long time ago, that the low frequency vibrations generated by the Saturn V at lift-off, would cause internal rupturing in large animals, up to around a kilometre away.

It also described how sound changes above 194dB, because the acoustic energy is so high that it overcomes atmospheric pressure - which is why rocket sound is a sort of crackle.

From the same book, about density.
A cricket ball weighs roughly 160g.
One made of lead would weigh 2.2kg.
One made of gold would weigh 3.8kg.
One made of osmium would weigh 4.4kg.
One made of plasma from the centre of the sun would weigh 31kg.
One made of neutron star material would weigh 200,000,000,000 tonnes - about the same as Mount Everest.

From the same book:
If you had the visual acuity of an Eagle, you'd be able to spot an ant on the pavement from the top of a ten-storey building.
Rather than keep quoting from it, I'll give it a plug - author is nothing to do with me for clarity. And ignore the rubbish title...

Did you brush off all the dust and cobwebs, before posting that?

From The Sky at Night this month - Jupiter's Great Red Spot is almost certainly not the one originally spotted in the 1660s.

The clapperboard seen at the start of filming is for synchronising sound and vision in the editing room, as these were often on separate reels - seems blindingly obvious now I have read it in Ade Edmondson's autobiography, but I'd never thought about it.

Tommy Two Moons
From the 29th of this month, Earth will temporarily have two moons, as we gain an orbiting asteroid for two months.

Earth will briefly gain asteroid as second moon, scientists say
Earth is about to get a second moon for a couple of months, but it won't be visible for most people.

I think the fact that they describe it as a 'moon' tells you all you need to know!
I love looking at the moon.
