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!
1 Since it is constantly changing from solid to gas, it has a very short shelf-life. 2  Every 24 hours, 5-10 pounds of dry ice turns from a solid to a gas. 3  Though most people can buy dry ice, some stores will require you to be at least 18 years of age in order to purchase it. The thicker insulated your cooler or ice chest is, the slower the dry ice will sublimate. 2  Open and close the container as little as possible to slow down the sublimation process. 3  You can also fill the open space in the cooler with wadded paper to limit dead space and slow down sublimation as well.
