Step 6: Plan a campaign

Now, find a building or structure that will attract the magnets, form a crew, wait until night, and get some throwies up. If you do it around a crowd of people, they will probably try to get into the act. It can quickly dissend into chaotic fun. Give a hand-full of throwies to a stranger and let them get up too. Remember, Throwies are only a temporary alteration of your local environment. Depending on the color, Throwies can last upto two weeks, but you arent going to cause any permanent damage, so most property owners wont mind. And The NYPD loves throwies!

i made mine waterproof
Is waterproofing necessary? I think the only reason electronics have problems in water is short-circuiting. With a simple circuit like this and at such a low voltage it shouldn't short. Either way, that's awesome. Now i want to see how buoyant they are and put 50 in my pool.

how long would the batteries last?

how can they be a temporary alteration? They will still be there even when the battery has run out as the magnet will hold them in place, they could be too high to be removed.

LM3909 (best IC for a throwie & many other uses) is no longer manufactured, so sign this petition to get it back into manufacture! http://www.gopetition.co.uk/petitions/start-manufacturing-the-lm3909-ic-once-again/sign.html
 Why not just use an all in one blinking led?

I suppose you could buy rechargeable button cell lithium batteries, and just reuse them after use.

What do we do with the batteries after finish? I hope it will not go to contaminate.
I, too, am looking for something to do with the batteries once they die out. I have very limited options since recycling isn't very common where I live. Is there a place I can mail them?
That's funny. I work at The Half King. Guess I wasn't around to see that.
