A Japanese company called ALE Co is bidding to handle the pyrotechnics at the opening ceremony of Japan's 2020 Olympics, and the key to its pitch is that it isn’t just planning on using fireworks like everyone else, it wants to fill the sky with hundreds of colorful shooting stars. If it gets the nod, this display would be visible from far outside Tokyo, up to 100 kilometers (62 miles) away. A meteor of such high apparent brightness would be potentially dangerous, but the company says that’s not a concern with its chemical payload.
