If you received a bunch of flowers last night (lucky girl!) and if you're desperate to keep them fresh for longer, here is a tip on how to achieve that, with no effort at all. Just make a mental note to drop into the vase two or three ice cubes each day while brewing your morning coffee. The ice will have a very similar effect to the fridge trick, so this way you'll be able to enjoy your Valentine's Day treat for a few extra days.
Btw: What flowers did you get?
