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!
Storage instructions. 1  Dry Ice will sublimate into Carbon Dioxide (CO2) gas. 2  Store Dry Ice in an insulated container-the better the insulation, the slower the Dry Ice sublimation. 3  Do not store Dry Ice in a refrigerator or a freezer (unless the Dry Ice is being used to maintain the proper holding temperature).
