Question: What medium should I use to create a large (happy birthday) message on the street!?

My girlfriends birthday is coming up and I wanted to leave a huge
"HAPPY BIRTHDAY BRIANNA"
on the street!. Her bedroom window faces the street and when she wakes up she would see it!. But I don't know what I should use to do it!.!.!.

I was thinking about using chalk, but that would take a LONG time as this is going to be really big!.

It needs to be something that will wear off and is biodegradable (I don't want to get into trouble for this lol)

THANKS a lot! :DWww@QuestionHome@Com

Poster paint (also known as tempra) is water soluable and is available in cans, jars, wet and powdered form at most art supply stores!.

Get some cheap paint rollers and disposable roller paint trays from a local hardware or paint store!. You can paint wide swatches of color with the rollers and can get done fairly quickly!.

It will wear off within a few days, or wash out with the first rain!. It is made from organic substances (such as eggs) and will biodegrade very quickly, without poisening the environment when it is washed down the sewers!.

As far as getting into trouble, that may be between you and the local cops!.Www@QuestionHome@Com

Silly string also washes away!.

YOu could try kool-aid ice cubes because they melt away and, they're super colorful!. Seen it done before!. Buy xtra trays at Goodwill!.

You could cut out the letters from cheap poster board, then tape aluminium or steel wire to the back and plant firmly into the ground on her lawn!. Good luck and happy Bday to her as well!Www@QuestionHome@Com

I agree with Md fisher,!.!.!.!.use chalk, it'll wash away and you won't get into any serious trouble!.!.!.!.!.!.!.or, you could use a pesticide sprayer and get some water based paint like tempera paint or finger paint,!.!.!.!.put it in the sprayer, mix some water to thin it out a bit and pump that baby up and get to painting!.Www@QuestionHome@Com
