Two-liter bottles, any ideas?

I've been collecting two liter bottles for a bit, and can't think of anything to create with them..
does anyone happen to have any cool ideas they would like to share?

PS: any ideas on what to make a large peace sign out of, for my wall of my bedroom?

i was thinking using scrap metal, but it might look way to tacky.

 

Cut them in half, poke some holes in the bottom, and start flowers from seeds to plant in spring. Or recycle them. Can't think of anything arty that wouldn't look like trash hanging from your wall.

 

for you peace sign wall thing you could use the bottle caps and paint them... how many ~ do you have?

 

i vote make a composter

 

most hardware stores will have feeders that attatch to empty pop bottles - it's a small thing that's no more than a couple inches big, and it screws onto the end where the cap normally goes, and there's a stand on it where the bird can perch, and a space to allow birdseeds to fall into. So, all you need to do is fill the bottle with birdseed, screw one of these things on it, and hang it upside down in your garden.

 

take them and wrap them in rows to make cubes and wrap those in cloth or duck tape and u can make furniture we made a couch and a chair and a table its a good way to recycle them u can also make at least 5 kinds of water pipes to.

 

Make a raft. It's not art, but it's loads of fun.

 

I second the raft suggestion!

 

you cout cut off the bottoms and paint them or something and make the peace sign then, that might look cool. uhhh.... you could maby hang em from your ceiling and paint the insides or something if theyre clear. idk. that might just look weird, - but something i would do.
like 50 of thoes 2 liter water tornado things lol... thats a waste.

i like the heating thing though...

gbong

and i guess you can make bird feeders too (pretty cool i think)

cut them across to make circles (even make some thick, some thin, some in the middle) make to holes that's across from each other in the circle(that make any sence), spraypaint or paint them different colors, and either make it wall art or like a room (or doorway) separator......

 

cut off the end, put a couple inches of dirt in it and stick in a candle for a nice lantern.
you could also fill them with water and store for emergencies.

 

Hey, check these instructions out for making a vase, they are very clever and pretty: http://www.wikihow.com/Make-a-Vase-out-of-a-Plastic-Bottle

 

If you have a large and a small hole punch (and a lot of time) you could make sequins...
