Roof Coffee Cup

Roof Coffee Cup
After reading a post on Gizmodo about a researcher who sent a student riding through college campuses dressed as a clown riding on a unicycle, and how he found people who were on cell phones/using electronic devices were 50% less likely to notice anything unusual happening, I got an idea. 

People maintain driving with a cellphone doesn't distract them.  I decided to see if that was true.  I thought and thought about what I could do to prove it.  Then it hit me.  If I put something on my car roof, I could see if people notice.  I decided a coffee cup was the best choice, and after consulting my friends, they said to go with a StarBucks cup w/attached "cup condom".  I did , and the reaction was good enough for me to give the cup its own Twitter feed( twitter.com/RoofCoffeeCup ), where I jot down what people do while driving, then Tweet a recap later.  It's hilarious because I can be driving at 65 miles per hour, and people don't consider how a cup could still be on my roof.  When I take turns in front of them, and the cup doesn't move, they still tell me.  Even at stop lights, when people get out of their cars and try to take it off, some people don't figure out it's not real.

With how hard it is to keep a straight face because I'm laughing so hard, I knew I couldn't keep the fun to myself.  I also wanted to see the RoofCoffeeCup spread out from the small area of New Jersey I drive, and go across the country.  Thus, I'm making my first Instructable.  All I ask is that if you do make a RoofCoffeeCup, please tweet what reactions/where your cup is using the #RoofCoffeeCup hash tag, so we can all share the adventures.

Now some "legal" stuff.  Even though the cup weighs 3oz, the magnets used are hard, and could damage should it fly off, and someone is tailgating you.  Check your local laws before attempting.  The magnets I use are stronger than the ones on those "tear-drop" lights some people put on their roofs, and this cup is lighter than those lights, so if those lights are legal, I don't see why this isn't.  I take no responsibility for anything that happens to you if you try this.  I'm only responsible for when I do it with my own car.  I'm not responsible for any damage to your car through possible scratching or dents if you drop it close to the car.  Don't be a hazard to others on the road.  The reason I went with a coffee cup is it's not that out of the ordinary, and it's not a danger to anyone, like if I attached a laptop or something else heavy.  It also will not cause a panic/calls to police, like doing this with a baby carrier or car seat would, which I DO NOT endorse trying.

A coffee cup is cool, but do you know what would be EPIC? A BABY CRADLE!!! Some with no sense of humor might not see the comedy in that however.

the day i get my car im doing this :D
it could be kind of entertaining to do with say, a cell phone, but perhaps have it "resting" on the edge of the trunk lid :3
id do it with a dummy phone though, you never know if someone would be "courteous" and walk off with your $250 smartphone.

nonetheless, i LOVED reading this. just think of all the things you could up ontop (or maybe even on the side) of your car!

PS: you could do it with a laptop if you took all the internals out and just used the shell ;)

I live around the NY/NJ area, and saw a car with a coffee cup on top the other day. I reached out to see if it was stuck on there with magnets. It wasn't, and then the guy who's coffee it was walked up behind me and said "What are you doing?". Quite embarrassing! Great 'ible, though!

Oh man , I would have thanked you , I hate it when I leave a cup on the roof .

Best way to separate the magnets from the backing:

Wouldn't Super Glue work too? You can just superglue the cup on to the car, but you'll need a solvent to remove it. Wouldn't it work? Oh, and by the way, NICE instructable. I am thinking about doing this to my mom and dad's car next April...

I like the magnets I get from dismantling discarded microwave ovens. There are two big, strong round ones on the magnetron that might just fit inside the cup.

I'm pretty sure you have to be 13 to sign up for this site. Now go get your mommy or daddy and have them shut off your computer.

This is a very funny idea! Somebody mentioned using a woman's purse. I have one up- how about an infant car seat with a doll inside!!!!!!!!! THAT would make people sit up and take notice- or, on the sadder side, maybe not!

The car seat is a very, very bad idea.  You could actually cause accidents, absolutely FLOOD the 911 system with bogus calls, and potentially be arrested.

and if you go under (get ready for something you've seen on tv) a low bridge it could fly off go through there wind sheild and kill them (ok maybe not the last part)

You can get strong magnets from an old hard drive. Simply open the HD case, poke around with your metal pliers, and you'll find them when the pliers stick to them. There are 2 magnets, at the base of the read/write head.

My magnets are so strong they can open my full-size fridge door, like a door handle.

I think a dalek would look good on my roof
Feb 4, 2010. 7:58 PMChrisdalton says:
I think it would be cool if you put a spring or something on the bottom of the cup (in a way so that it cannot be seen) so that when you turn or stop the cup leans and looks as if it were about to fall over but once the g-forces return to normal it goes back upright

       I just finished mine today, and am very happy with the results. I took it for a test drive around my neighborhood, and  down some big streets, and oh man the looks and gestures I got were HILARIOUS! I had one guy practically running from his parked car waving his hands and pointing while screaming his head off, I was just trying to not crack up :D  

                                                Thank You for the great instruct-able!

HI,
          I have one question, How did you get the hard drive magnets removed from there mounts? Also I wanted to say that it would be funny if you put brown liquid in the cup and let it slosh around, THAT would get some funny looks LOL!
Jan 7, 2010. 12:12 PMJakeg says:
Thanks I'll try this and make the roof coffee cup soon!

*heh heh*  I'd seen that before.  I'm wanting to say he DID get ticketed, but it was worth the price as it was an advertising thing.
Nov 19, 2009. 9:21 PMfangmike says:
You should put a fake "for sale" sign in your car window and have your cell number or a number that you don't mind getting a lot of voice mails...then you could see if people try to call you and alert you about the coffee cup.
Dec 23, 2009. 8:58 AMJavin007 says:
LOL!  I like that idea, except that would then give them a REASON to get on their cell phones.  Could get you into some trouble.  Particularly if they get ticketed for being on their cell phones and come after you.  This is the day and age where you can sue someone for injuring yourself while robbing them, afterall.

there was a recent psychology film showing maybe 6 students throwing 2 basketballs to each .

the lecturer tells you to focus on counting how many throws are done during the 1 minute film.

most people say 35 - 40 throws.

http://viscog.beckman.uiuc.edu/grafs/demos/15.html

watch it.

count the the number of throws.

don't read any further until you have seen the film






a few people might say "why was there a gorilla in the film?"


Dec 22, 2009. 10:25 AMetymological says:
I wonder how many people, like me, notice the gorilla (or whatever else is odd about the situation) and simply choose not to say anything and to just answer the question presented.

strong magnets to hold 10 lbs.

lol i find it funny that no one would actually set a starbucks cup on their car. most people would get it from the drive through. haha i was cracking up after reading the intro.

RoofCoffeeCup guy tells us how it all got started, what's next, and if the cute chicks are taking the bait in our latest podcast at http://www.lessernerds.com/

When I saw this I had to try it!!!  so I did...  Totally awesome!  One guy this morning actually stopped at an intersection - in front of me -  when the light was red, stepped out of his car, jestured and pointed to my cup.  I then showed him the coffee cup I was actually drinking from and he just cracked up!!!  LOL    By the way, I have taken my cup upto 75 mph or 120kph no problem at all (on a closed track ofcourse).  The key is to have the magnets in direct contact with the rooftop.  My lawyer says its up to the discretion of the officer if you get a ticket or not, so be aware.

Great Instructable!  Just Love It!

Nov 19, 2009. 7:14 AMbigtreehouse says:

I am not a coffee guy... I am more into soda... I can just take a half full Mnt. Dew bottle and drop in some magnets... and I am done.

I was thinking a beer can would be funny.

Nov 28, 2009. 6:36 PMKarred says:
 sadly even when fully drained a beer can is still considered 'Open Container of Alcohol' and  will get you a ticket! T.T
