Magnetic Eyeglasses

Today Mom sent us a photograph of her fetching new glasses, and while on the phone with her she mentioned being glad that the frames lack those annoying nose pads that leave marks on your face. 

That gave me an idea. Surely a skilled surgeon could mount a small, subcutaneous iron plate on the bridge of your nose bone for the express purpose of holding a pair of magnetized glasses on your face. Just think of it: A magnetic bond of the right strength could hold your glasses securely to your face without annoying nose pads or arms, increasing comfort and convenience while reducing the cost of eyeglasses. Brilliant, no? Mom thinks I could be a millionaire if I market this.

Or maybe she was just humouring me . . . a lot of people do that. 

Animated Real-Time Globes

Sometime in the not-too-distant future, someone is going to invent a globe that's connected to the Internet and has some kind of drawing capability so that the globe can update national boundaries, country and city names, and so on, in real time. For example, if we'd had this technology in the 90s, it would have shown the borders changing as the Soviet Union and Yugoslavia crumbled. More recently, it could perhaps show the shifting fronts of the Syrian civil war, or the disappearance of North Yemen, Eritrea's liberation, and so on.

I'm pretty sure the various technologies to create this probably all exist; they just haven't been combined into my realtime globe. Someone invent this and I'll buy one! 

Building a Better Ray Gun

Someone should invent a toy ray gun that has a real laser, but also a water reservoir. When you pull the trigger, the gun shoots a fine mist of water just before the laser flares into life. The result: a visible laser beam! How cool would this be?

Alternatively, you could just put lasers on squirt guns for a similar, though not identical, effect.
