If you e-filed your return and are expecting a refund, you should get it pretty quickly. The Internal Revenue Service says most refunds are issued in less than 21 days. That's assuming your tax return is complete, has no errors and is not affected by identity theft or fraud. So if it's been more than 21 days and you haven't seen any sign of it, the IRS gives you several ways to track it down.
How long does dry ice last? The question of how long does dry ice lasts does depend somewhat on the purpose it is being used for. As a general rule, it will last for 18-24 hours in a cooler or ice chest, 3-5 hours outside and 15-45 minutes when reduced to a liquid form. If you are storing it in a cooler, make sure it is not an airtight one as when the ice melts, the gases could cause the cooler to burst!
Please try again later. This is a follow up to my where to find dry ice for camping video. The dry ice held up till 3 1/2 days after we picked up 20lbs of dry ice from a local Safeway supermarket. Also remember that the cooler was stored in the shade from our tent in an average daily hi temperature of 90-100'F and average daily low of 65-70'F. The cooler we used was an igloo 50qt 5-day cooler. We may be trying this experiment again in early September when we go camping again and the average temperatures will be 15'F lower. Hopefully the temperature drop has an effect on the longevity of the dry ice in the cooler.
