Great Binoculars | The Wirecutter

If I needed binoculars for zeroing in on birds, fireworks or the people in the building across the street, I'd get the Nikon Monarch 8x42mm. The glasses cost about $250, but you could spend a lot more and have little to show for it, or spend a little less to lose a lot. The Monarch's rugged, waterproof design, and its light weight and superb optical clarity under all types of lighting, have earned high praise from ornithologists, hobbyists and retailers alike.

I don’t quite understand people who can’t take care of plants. But I also feel bad for people who can take care of plants but travel a lot. These electronic boxes manage watering automatically, and even remind you to refill the water reservoir. Extraseed packs, which range from thyme and mini tomatoes to flowers, are \$20.
