If you're given a chance to invent something, what would it be?

I want to invent the fountain of youth. Don't you think it will be fun to be with the one you love forever.

Ever since I watch the movie "Back to the Future", I have always hoped to invent a time machine. It will allow mankind to travel to and fro in time. Only condition, no changing of history is allowed during such travel.

I would want to invent a time machine so I can travel to the future and see how it turns out.

I would like to invite a digital camera with bluetooth so we can just share photos with each other without having to download the photos in a computer. Hear, hear, camera manufacturers out there!

I was bored when I thought about being the owner of an ultra perfect defense mechanism that even my eyes can control. By then, safety will be a lot easier to achieve.

I want to invent a collapsible vehicles. It's the best solution to traffic! For example you have a car, and you're stuck in a traffic jam. You're running late and you're just a few minutes away from your destination. You wish you could just walk there, but you can't leave your car! So what you do is press a button inside your car and get out. Once you close the door, the collapsing mechanism will activate and your car will shrink into this small "model" car. Like a matchbox version of your car, only about 4x bigger than the regular matchbox. So now you can put it in your pocket or your bag and get going. Then if you need your car again, just drop at least 3 drops of water! We wont need garages and parking lots anymore! YAY!

I would like to invent, "Time Machine" so that I can travel in time.
