Pinterest Deal or Dud?

I absolutely love Pinterest. But one thing I get frustrated with is that most people I've found just repin without changing the caption. So I have 10 people I'm following all posting a recipe that says that they've made it 10 times in the last month and everyone has kept requesting it. So I never know who actually made it 10 times and whether or not their recipes are tried and true. I have tried at least half of the things I've pinned, but I don't actually have a way of reviewing them on Pinterest, so I thought I'd do that here.

So the first pin I absolutely love is this. Did you know that, once you chop the green stems off green onions, you can simply put the whites/roots into a glass of water, and the greens will grow back?! I've done this since Thanksgiving, and it's worked every time perfectly. I even had 2 onions that I kept, used, and grew and re-grew for over 2 months. They don't have to be in the light, the temperature can vary greatly, it doesn't matter if they're in a draft. The original pin said they'll grow about an inch per day, but mine grow at least 2 inches per day. It's amazing and so convenient. Try it!
