My favorite video was ALL OF THEM=http://=http://=http://!!! I liked them all because they are FUN STUFF=http://!! 

Yes they are working because I saw them working in the video. That is how I know they work.

My idea is WASHABLE CARS

Once the car gets dirty turn on the window wipers and car washer button. the car washer button will release GIANT window wipers to wash the WHOLE CAR=http://!!!!
