Scallion regrow device

It’s amazing! Leftover onion roots will regrow within a week or so to a complete brand new set. Just chop the roots off a little bit longer and put them in a glass of water. Make sure you change the water out once every couple of days so they don't get greasy. If you tend to top your food with green onions a lot, this is a pretty simple way to ensure you always have some around.
With this Thingi the regrowing roots will stay upright.
The glass is recycled from an Ikea scented candle. Height of the glass is 90 mm. Inside diameter on top is 73 mm.
Have fun!
