 It's time for today's STEM tip. Okay, you know recycling is important. No one wants plastic in the ocean. Here's a cool way to repurpose a plastic bottle. Build an awesome terrarium.

Put the top of the bottle over your base and place it in the sun. Your plant will grow sealed in its own ecosystem. Fun, right? Learn more at SheCanSTEM.
