If you have ever used Visqueen to insulate a window, and half the folks in Florida either have or know someone who has, bubble wrap is the way to go. You can substitute bubble wrap for Visqueen.
As an insulator, you can apply bubble wrap to the interior of a box to store supplies. You can also wrap items in it separately to help protect against the cold while in storage.
Use bubble wrap to line the crisper drawer in the fridge, no more bruised tomatoes!
Line the inside of plant pots before adding soil to grow those winter herbs inside on the window sill.
Wrap the out side of plant pots with bubble wrap allowing the wrap to extend a few inches above the lip of the pot to insulate against a winter frost.
Bubble wrap comes in colors. The clear wrap can be painted while on windows to decorate the room.
TIP: the flat side of the bubble wrap goes toward the outside of your project. The bubbly uneven side goes against the window glass, the item to be insulated, the item being packed, the veggies being cushioned.
