thanks for your reply. Would tungsten putty work by any chance? A complete guess

Hi, Just wondering if there is anything that you can paint or stick onto the 'attracting' part of a magnet to stop it being so magnetic? thanks

excellent guys, thanks. I will do some further searches on your advice. Thanks again

Sounds good but I kind of need it to be as lightweight as possible and portable. Any other ideas? Thanks for your quick reply by the way

Hi, I am after some advice from you guys, it would be much appreciated.... I am looking for your recommendation on the best material that when placed out in the sun all day would have heated up very well and then continue to hold that heat with not much loss (or very slowly) all through the night, so that are small area could be heated Any ideas? I have been looking at cast iron which seems good but to be honest it's one of the first I came across! So I thought i'd approach you guys for more expert advice, You suggestions would be much appreciated and thanks in advance. oh, a lightweight material would also be an advantage, thanks

Thanks YT2095 for your reply, much appreciated. So, if the container wasn't sealed and the liquid was allowed to evaporate, what liquid (preferably safe) could be used?

Hi, excellent forum you have here! So, my question is one that has been on my mind for ages and I was hoping that someone could please put me out of my misery..... Is there such a liquid that stays cold even if it is heated? For example, say the liquid was contained in a beer can, completely sealed and then put in a hot atmosphere like an oven, is there a liquid that you know of that will stay cool? Thanks in advance and I look forward to your replies
