<p>eat cold things. Fruits, ice cubes, ice cream, nibble on frozen vegetables like peas and let them thaw in your mouth (not as gross as it sounds)</p>
<p>ice packs. get like three or four of them and make a rotation so you can go back to the freezer every 45 minutes or so and switch them. you’ll always have a cold one this way</p>
<p>Seeing as you said you have limited resources I’m assuming you only have 100 kilograms of gold, 100 barrels of refined oil, and 50 kilograms of flawless cubic zirconium. To start off, take all of your cubic zirconium and give it to a run down pawn shop. Make them beleive it’s real diamonds, and if they say it’s fake take it to a different shop. Repeat the process until one buys all of the zirconium.</p>
<p>Take your profit and invest it in exxon stock. Then, after converting all of your gold into currency, use the money to bribe your way to the head of OPEC. Donate all of your barrels of oil and remaining money to him, and convince him to use this oil to temporarily lower the price of gas in America by 25 cents. </p>
<p>Quickly, stowaway on a cargo plane home. When the price of gas is lowered, sell your stock at a high price. Use the fortune you made in the stock market to buy a house on the beach, and a few barges. Use the barges to tow a glacier directly beside your house. Rinse and repeat everytime your glacier melts, and by the time all the glaciers are gone, mother nature will have compensated and lowerd the temperature of the entire Earth, making air conditioners redundant.</p>
