So they don't need to get much from elsewhere.

I bet "transition metal" is a better phrase.

How much energy do you think the bird needs?

Bird goes up. That means doing work against gravity.

The dandelions in my garden disagree. So do lots of birds.

The process of a dispute over pay doesn't damage cables. What actually happened? Some of the early research done on the subject was on people doing piece-work in factories. I don't think burger flipping is very different. The experiment was actually very instructive. They got a group of workers and found out how many items they made in a day. Then they reorganised the workplace and measured productivity again. It had increased. The management concluded that the changes had improved productivity. But the scientists were wiser than that. They waited a while an d then measured productivity yet again- and it had fallen more or less back to where it had been. So they swapped the workplace back to how it had originally been and, yet again, there was a temporary jump in production. It turns out that changing things makes people more interested and more productive. Further experiments showed that teh changes didn't have to directly relate to work. Starting a chess club would have an effect. Now, imagine the young burger flipper who gets a pay rise. He's going to make changes- possibly even joining a chess club. So, I can see a pathway , based on research (in the 1950s I think) by which a pay rise would improve productivity. The interesting question is can anyone think of evidence for why it would not do so?

That's more or less what the Conservatives said when the UK was considering introducing a minimum wage in 1999. They predicted mass unemployment, destruction of the economy, plagues of frogs etc. None of which actually happened. It's as if the political Right wing don't tell the truth about things.

A hot air gun is probably the option that minimises exposure to nasties (including lead). It leaves any lead compounds in a sticky painty mess which falls on the floor and can be disposed of. An abrasive will turn it into dust which will get everywhere including your lungs. Get a fire extinguisher, just in case. I think a hot air gun is the cheapest option too. One vital point. Do Not Combine DCM And Either A Heat Gun Or A Blowtorch. You will generate phosgene. (DCM is bad, but nobody ever used it as a war gas.) It's obviously possible to add some chemical to CDM to thicken it- because the manufacturers of paint stripper do just that. But I don't know what they added.

What's funny is having a town named Dildo in Canada,

Are you sure you really want to say that? The alternative is that you are dishonest. Because your idea can not work.

You are here and therefore you just called yourself uneducated. That my be the most salient point you have made. Anyway, if you don't like the membership of this forum, you will be delighted to know that we won't force you to stay.

Really?

A virus is not a cell. And the rest of your posts are equally wrong.

There's an interesting phenomenon that you may have observed. If you have a sheet of fluorescent plastic, the edges seem to glow brighter than the faces. It's due to internal reflection. The amount of light emitted is the same from all teh faces, but the smaller faces are brighter.

Obviously,I should know better than to sink to this sort of thing; but it's funny.

It may be closer to human hair than Michael Fabricant's "headpiece". https://www.indy100.com/politics/is-michael-fabricants-hair-real He says it's real but he's a politician and even his name means "someone who makes things up".

Doh. Misread something.

No, it doesn't. If you want to discuss statistics that's fine. But starting with a false statement is just going to distract people. This isn't any better.

If it's a detonator, it only needs to work once. So it's a slightly different scenario. But, since it's a detonator, I'm not going to help.

I wonder if there's a geometrical solution.

Seawater is typically slightly alkaline, but poorly buffered. There isn't much in it (apart from salt). So adding small amounts of acids or bases to it will change its pH by a large amount. And, if your red cabbage indicator has much vinegar in it, you will overwhelm the small amount of alkali in the seawater and the mixture will end up acidic.

WiFi.

This is about the best I can think of as a quick way to grow stuff, but it's not the same thing https://en.wikipedia.org/wiki/Chemical_garden In principle, it should be possible to make a system that drives carbonated water through crushed limestone and then let that solution lose CO2/ evaporate and deposit CaCO3.

The tables I posted a link to are for sucrose. Golden syrup is a mixture- it contains quite a lot of invert sugar. Also, you could measure the density; why would you want to?

If I want to find a definition of it I can just Google "define physics" and it will tell me. I can do thr same with biology or chemistry. But those words are longer so, in terms of how many letters I have to type, it is actually easier for me to get a definition of physics. Incidentally,if you are going to garble a joke to make your point, you might as well include the original. “If it squirms, it's biology. If it stinks, it's chemistry. If it doesn't work, it's physics. And if you can't understand it, it's mathematics.” ― Magnus Pyke
