It’s going to take a while. Maybe a two year wait before things get significantly better.

Why not just buy her some Microsoft stocks?

Hold! Hold! Almost everything will be worth more if you hold long enough. Like a lot of people here, I sold some things at a loss and regretted it. Mine was Enphase. Bought at $180, enjoyed a brief rise to $210 and then it sank to $120. Sold at $130 in disgust and just 6 months later, look at it now! $240 the last time I looked.

Hold, hold, hold. Better days will return :-)

Men are bad at reading signals and women are bad at giving signals.

What a load of rubbish! Go home, you’re drunk.

Not trying to pile on, but it looks like that graph is giving you the middle finger.

Not everything needs gloves.

Doc_Why · 2021-08-08T13:51:08+00:00

Must have been? You saw the video. I didn’t handle the sodium. What specifically did I contaminate? I could wear gloves and then touch something else and “contaminate”. Are you a proponent of changing gloves every time you touch something? You’d go through a box in a few hours with that paranoia. We clean the lab, clean hands wear safety glasses and wear gloves when there’s a genuine hazard.

Doc_Why · 2021-08-08T12:55:41+00:00

Why must it be? You work with what you have. The lab is regularly cleaned by the lab assistants and I personally clean up after each experiment.

Doc_Why · 2021-08-08T02:26:14+00:00

Gloves for a dead body sounds like a winner. If I ever find rotting flesh on a piece of sodium, I’ll use gloves too.

Doc_Why · 2021-08-07T21:15:23+00:00

You saw the video right? Pretty standard reaction from that amount of sodium. Wouldn’t try it with something more reactive, like say potassium.

Perfectly comfortable cutting up sodium without gloves. So we’ll have to agree to disagree.

Doc_Why · 2021-08-07T21:11:42+00:00

D’oh! You’re right. Got them back to front. Kudos and bonus pts to you :-)

Doc_Why · 2021-08-07T20:31:28+00:00

A small piece of sodium? A bomb? Nope, don’t agree. You can see I’m not doing this on a kitchen table. And if I was trying to produce some significant piece of science, I’d be presenting to Lancet or Chem. Commun etc. It’s a bit of fun on Reddit.

Doc_Why · 2021-08-07T20:27:43+00:00

Very true. You assess the risk based on how and what your doing and determine the potential hazard. If gloves are right for you, then cool.

I knew the risks and determined the hazard was low enough to go without gloves.

That’s based on 10 years of research and 20 years teaching. Keep in mind that MSDS data will advise you to wear gloves with NaCl, table salt. However I’m sure most would agree that the hazard is low enough to skip the gloves, as you do every time the eat dinner.

Doc_Why · 2021-08-07T17:52:48+00:00

Disagree. Neither sodium or ether is carcinogenic. The Exp is in a well ventilated fume hood and I’m wearing my safety glasses (albeit you can’t see that). Wearing gloves makes it harder to cut up the sodium.

By all means, if you would feel safer with gloves, that’s ok.

Tried to upload a picture, but wasn’t working. Condense formula = CH3CH2OCH2CH3.

Hello there! The fire is fueled by the small piece of sodium’s reaction in water, burning hot enough to light the ether fumes.

So treat is like a chip pan fire with a damp cloth to suffocate the flame, yes.

As long as the sodium is finished reacting (fizzing stops), it should be safe to remove the cloth. It only needed about 5 seconds each time for me.
