I Wish Someone Would Invent.....

time machine so that we know how earth and us (mankind) come about...
so we can settle the disputes for all religions once and for all

a better space ship that will find us another EARTH or 2 more....
so that everyone will have their lands and never go to war on petty resources

another life on some other planet that we know we aren't the only ones....
so we will actually unite as a species (mankind) instead of fighting or warring over things like differences in countries, religions, cultures etc.

another "Einstein" that will make all the above happen!
 
Okay, here goes crazy idiotic...

-- An injection into the brain for speedy learning (1 shot of calculus, please).
-- A poke ball thing that zaps a pet into happy land for convenient travel
-- Better yet, a teleporter
-- A laptop that folds into my pocket but unfolds to be full size


I second the noiseless vacuum (a powerful one, not the kind that restaurants use when people are still eating there).

I know this is stupid but... I dog leash that lights up or glows in the dark. So at night people can see us when we are walking.

Btw, I think there's a lot of these if you search on ebay...maybe not as nice as you imagine but it serves some purpose:
