I grabbed some Forever Bags at Menards a couple weeks ago. They were free after rebate, so I thought it was the perfect time to try them. The first thing I tried was bananas.
I had 6 bananas in one bunch, so I put 3 of them in one of the bags and left the other 3 out on the counter. After 5 days, my bananas looked like this:
So, there was definitely a difference. Unfortunately, I stopped paying close attention after that. I left the bananas in the bag for several more days, and then I noticed that they were turning a little brown - and they were soft. They weren't as brown as the bananas that weren't in the bag, but they were just about as soft - so I'm not really sure the bag made much of a difference really.
It wasn't a huge problem. I just made some banana muffins.
I'm really interested in seeing how these bags work on other things. Right now I have some bell peppers in one and some chard in another one. We'll see how well things keep.
