Pretty good crash.. Tesla, a model boat, but the year was 1898 .. the man was a genius, far ahead of his time, and I feel a lot of his work is yet to be developed or understood.

Yes Tesla was the obvious choice. He really was a genius. You people have all kinds of info available to you. Good job!

Turnips were the original not pumpkins, but I don't know the other 2 answers. It is amazing how you can remember snippets of useless info, but not the overall story.

Irish?

Before the Empire State building was built.
What was the tallest man made structure in the world???:confused3::confused3:

Farm Girl I'm use to being wrong. Nothing new there. :laughing::laughing:

Maybe Eiffel Tower?

Hi Harry,
... It is our moon. One side is always facing the sun. In a deep crater on the back side they have discovered water ice that is almost absolute zero.

One side is always facing the Earth, not the Sun, so the Moon does have a day and night. Water was found near the poles.

Hi Harry,
Mercury is not correct. It is our moon. One side is always facing the sun. In a deep crater on the back side they have discovered water ice that is almost absolute zero.

Titan does have ice volcano's.

The moon always has one side facing the Earth, not the sun so it get direct sun light on all faces during its rotation.

Mercury was thought to be tidal loced to the sun until about 1965. It does rotate but has one crazy "day" with sun rising, reversing, setting amongst other didos. Turns 1 1/2 times per orbit around the sun.

The Rotation of Mercury

I'll still put Mercury with the hottest and coldest temps differential.

You are correct.:thumbsup::thumbsup::thumbsup:
And before the Eiffel Tower???:confused3::confused3:

These spacecraft have contributed to confirming the discovery of lunar water ice in permanently shadowed craters at the poles and bound into the lunar regolith.

Similarly, there are places that remain in permanent shadow at the bottoms of many polar craters,[66] and these dark craters are extremely cold: Lunar Reconnaissance Orbiter measured the lowest summer temperatures in craters at the southern pole at 35 K (−238 ｰC)[91] and just 26 K close to the winter solstice in north polar Hermite Crater. This is the coldest temperature in the Solar System ever measured by a spacecraft, colder even than the surface of Pluto.

Minimum/Maximum Surface Temperature

I did not research Mercury, so I don't know about it.

Maybe pyramid?
