geko Posted July 20, 2004 Report Share Posted July 20, 2004 Hey gang! Didnt know where to post this (thought it might be a physics question or something, i dont know if it exists you see), but decided to post it in here for the safe bet. Anyway, im looking for a material that stays cold (about 5 degrees C) with enviromental conditions between 40 - 50 degrees C (or stays cold for quite a while; 1 hour plus). To be able to re-use it a number of times would also be good. The cooling process could be the fridge or water or whatever. It must be lightweight - no more than 5kgs for 2 metres square and (say) 0.5 cm thick. A metal is no good as it needs to be supple and malleable (the consistency of a water would be nice, bit thicker maybe so as not to be as runny). Ive googled this and it seems to get confused with whatever search terms i use (but will keep trying), and those that i have found that show positive results are companies that only seem to deal with large quantities so have said they will not respond (ah well). Any help would be much appreciated... truly. Thx Quote Link to comment Share on other sites More sharing options...
Uncle Martin Posted July 21, 2004 Report Share Posted July 21, 2004 What is the intended use of this? That info would help in my thought process. Quote Link to comment Share on other sites More sharing options...
geko Posted July 21, 2004 Author Report Share Posted July 21, 2004 I'm going to wear it. To keep me cool in squash tournaments. I cant tolerate heat (well, not very well). Quote Link to comment Share on other sites More sharing options...

geko Posted July 22, 2004 Author Report Share Posted July 22, 2004 Saline. Salt water? And thats because it has a lower than 0 freezing point yes? Sounds like it could be a good idea, not sure if it will stay cold enough long enough mind, but thanks, ill try it. Now all i need is an idea for tubing...... hmm, let me think Quote Link to comment Share on other sites More sharing options...
Uncle Martin Posted July 22, 2004 Report Share Posted July 22, 2004 IV tubing? Wrapped around points where your arteries and veins are closest to the surface should be good for an hours worth of cooling. Cool your blood, you cool your whole body.

Uncle Martin Posted July 23, 2004 Report Share Posted July 23, 2004 Helluva thought FT. Geko, if you're one of those gazillion dollar contract sports pros,.... we demand our fair share. Quote Link to comment Share on other sites More sharing options...
geko Posted July 24, 2004 Author Report Share Posted July 24, 2004 Sorry guys, im not on the psa circuit [yet ]. Havent been able to secure any A tournament wins sadly due to regular heat exhaustion (minor). 1 hour + matches in grueling high 20 low 30 degree temperatures - damn ridiculous (seems to be a UK tradition - dont ask). Bloody pi*sed off i get!! uh hum... sry bout that.. Not much money in soft ball anyway, getting better mind - give it 5 years or so i reckon.

Tim_Lou Posted July 25, 2004 Report Share Posted July 25, 2004 "Salt water?" hmm, how about the cooling liquid ppl use in cars??its poisonous lol... how about alcohol?? Quote Link to comment Share on other sites More sharing options...
Uncle Martin Posted July 25, 2004 Report Share Posted July 25, 2004 Liquid nitrogen would work well,...too well. You would need a winter coat and end up with severe frostbite. Quote Link to comment Share on other sites More sharing options...
Freethinker Posted July 26, 2004 Report Share Posted July 26, 2004 Tim has an idea, Something with a negative temp coefficient. Quote Link to comment Share on other sites More sharing options...
Tim_Lou Posted July 27, 2004 Report Share Posted July 27, 2004 hey, i found some cooling products on the internet:http://www.heatrelief.com/http://www.refrigiwear.com/CoolZone.htm Quote Link to comment Share on other sites More sharing options...
geko Posted July 28, 2004 Author Report Share Posted July 28, 2004 wow, those heat relief things look really good, much better than the 'ice vests' that ive used before (which dont work for me to tell you the truth). Head bands, hats, neck bands and tops! Great stuff Tim. Thank-you to all 3 of you. Much appreciated! Quote Link to comment Share on other sites More sharing options...
