I think lasers are pretty wack when you think about them through this lens. A small, wand-like object in your hand can make light appear from seemingly nowhere. If it’s powerful enough it can set things on fire or blind people. Not to mention larger ones like laser cutters or the LLD, used to destroy missiles midflight. Thats sure to blow some feudal peasant minds
For the birds, look for the Cornell Lab Panama Fruit Feeders. They have other cameras you can watch on the top of the page.
The beaches are in livebeaches.com but there are a lot of broken links there, so look around to check which ones work.
The Monterrey Bay Aquarium’s website has multiple live cams you can watch, and they’re pretty cool.
