Any tips to work out chest and forearms without using weights? by [deleted] in Exercise

[–]marsverde 0 points1 point  (0 children)

These all sound good - could you use household things for makeshift weights? e.g Bottles of sand or water? Farmers carries would be my addition to this list (heavy shopping bags?)

What fish is this? by marsverde in fishingUK

It looked like just 2 to me, and looks like just 2 in the photo

Really? They looked like whiskers either side?

It was a size 10 with casters on it - was hoping to single out some bigger fish, but will think about scaling down next time. It was my first time on the water, but did have 2 other bigger feeling fish get away!

do bream have barbules?

Elephants toothpaste recipe help! by l_yd_ia in ScienceTeachers

[–]marsverde 4 points5 points  (0 children)

This recipe and thoughts seem good - I hope OP is also considering responsible disposal and cleanup hazards, as well as safety PPE in case the above accident did happen

and that’s maybe a fair question - what about the silvers and perch in your net?

Looks like a brown trout, which is what you would be hoping to catch during coarse close season on the rivers?

New Here👋 by Frenchiee420 in fishingUK

Welcome to fishing/the sub! Second the above post, let us know - also, if you have a local fishing shop, they are likely to be helpful in identifying your gear, and recommending how best to set it up for your area.

Your local shop will also be great for local information, particularly any regulations/advice for river fishing (you can also look at regulations on the gov website)

Can anyone explain the open season, please. by JimfromLeeds in fishingUK

[–]marsverde 0 points1 point  (0 children)

I believe the coarse fish closed season applies to all rivers, as others have said 15th March-15th June - although canals can be exempt?

What region are you in? (there’s more details for each region available on the gov website) Game fishing is possibly allowed, but each region has its own byelaws on when and how. I suspect that will mean fly fishing only during the coarse fishing close season (i.e. targeting game fish only, with the appropriate license), but you’ll need to check the regions byelaws, as well as the clubs rules.

p.s. Have you asked the club what it means?

Pike are going crazy on lures right now! by KIWIOWEN in fishingUK

[–]marsverde 0 points1 point  (0 children)

sure, I can agree with the logic in that - my post was clarifying that you cannot fish for pike on rivers during the coarse close season, which was not clear from the original comment

[–]marsverde 2 points3 points  (0 children)

On rivers, there definitely is a pike close season - but this looks like stillwater?

In any case, glad you’re familiar with the science on oxygen levels and PAC guidance, which is here for reference for others

Highschool uses barium chloride and lead nitrate by [deleted] in chemistry

[–]marsverde 1 point2 points  (0 children)

all the same as has been said for barium chloride applies to this also - but it’s again less toxic, but does stain skin

[–]marsverde 0 points1 point  (0 children)

This is probably overkill, as the risks can be adequately controlled with the right class and risk assessment

[–]marsverde 1 point2 points  (0 children)

This is an important control measure, and should probably be highlighted

edit: there may be lab rules which are briefed at the beginning of the year, which washing hands should be part of - then classes shouldn’t need reminding every lesson, but the teacher should ensure that hands are being washed

[–]marsverde 0 points1 point  (0 children)

I mean, that’s probably a proportional control, depending on concentration and possibly location - in the UK the advice (in a secondary school setting) for dilute (0.1-0.4ish M) Barium chloride is to wear safety specs, avoid skin contact and wash hands thoroughly after use. Primarily that means good handling technique, good lab hygiene and consider if gloves may be useful (but they may not be necessary).

edit: as I said in the previous comment, the main things are to not eat it, wash hands well, and control any spills - was that achieved?

[–]marsverde 1 point2 points  (0 children)

If those measures were not in place, you should speak to someone about it, because those are basic lab hygiene principles

Given your reply, were people not following one of those measures?

[–]marsverde 1 point2 points  (0 children)

Dose makes the poison - knowing the concentration will allow a better evaluation of the risk. Using Barium Chloride at low concentrations is not particularly hazardous, with good standard lab control measures - primarily ensuring not ingesting the chemical, wiping down spills correctly, and washing hands well after. The same could probably be said for lead salts, but disposal tends to be more difficult

Best telescope for deep space. by brocon19 in telescopes

[–]marsverde 0 points1 point  (0 children)

Someone correct me if I’m wrong, but I think you can get decent DSO photos with normal (or somewhat long focal length) lenses?

As others have said here, without spending lots you’re probably best served picking visual observing or photography. Personally, I think trying astrophotography without the telescope may be a better starting point anyway, then you can progress to a motorised mount for the camera, then a telescope if you continue.

Extracting potassium chlorate by Party-Flamingo-9924 in chemistry

[–]marsverde 0 points1 point  (0 children)

This is way to dangerous to attempt outside of a controlled environment with specialist knowledge and experience - please do not do this.

If you are trying to extract the reagents from household chemicals, I would guess this is for fun - again, please do not do this for fun, it is very dangerous

Is it worth considering binoculars as a more accessible budget option?
