様態の副詞

Neil has finally done an experiment for me that I really wanted to see for many, many years.

A teaspoon dissolving or melting in a cup of tea.

I thought that in joke shops that you could buy a spoon like this, melted and T and I've bean to some of the leading magic shops in the UK and found nothing.

One of our viewers centers a low melting point alloy.

I went out and bought us Neil a mold for making spoons.

It's actually meant for chocolate, but it worked for this metal.

Then there were all sorts of delays, and yesterday we finally decided we to do the experiment.

But we've lost the letter, so we don't know chemically what the metal spoon is.

But we decided we'd go ahead anyway, and I'm going to have to analyze the spoon to find out what it is.

All these metals that melted low temperature, a so called Eloise, their mixtures of different metals which don't crystallize very well.

So at low temperature you can melt them much lower temperature than the individual metals, and they usually contained lead, sometimes 10 sometimes cadmium, sometimes indium and they're named after the people that have discovered, um, there's Rose alloy, which melts at 98 degrees, which I think is a bit higher than the temperature that Neil was using.

I don't think his tea was actually boiling.

It's 70 degrees, and there's field's metal at 62 degrees centigrade.

Cell sis, if you prefer, which oh, strong candidates.

I seem to remember that the fan who sent us the letter said that the metal contained indium and if it did, is probably field's metal.

But we'll have to test the chocolate mold that I had made a sort of spoon, but it didn't look quite as nice as we would have liked.

So I encourage Neil Toe hammer the spoon to look nicer.

But whatever this alloy is, it's very hard and brittle, and eventually he dumped it so hard that it broke.

So a spoon is not terribly spoon like, But what's interesting is that as he lowered it into the tea and she did it properly, there was a tea bag there.

He didn't taste the tea as he load it in it quickly melted and disappeared.

And at the bottom, the molten metal looked very like Moe Terry.

It's not mercury, but of course, most metals or silver or many of them on any silvery liquid metal will look rather like motoring.

When Neal decanted the T leaving the metal, the metal quickly solidified again because it cooled down.

I think the metals quite toxic, but I don't think any of it will dissolve.

Well, we would have lost our alloy and would never been able to analyze it easily.

 It doesn't have a great scientific purpose, but sometimes there's some scientific phenomenon that you've read about and you'd really like to see with your own eyes, so saying this was really quite exciting.
