Make some simple moss bombs to throw at buildings and add some living green to your urban cement-scape.
Step 1: Find Your Moss
Moss can be found in all sorts of corners. I found mine near an abandoned pool. You can also find it online, though expensive, at mossacres.com
Step 2: Gather Ingredients
6 cans of beer. (3 for your bombs, 3 for yourself)
1 box of sugar. (1/2 table spoon per can of beer)
bag of rubber balloons (heavy duty kind will prevent an explosion on your face)
moss (that you collected
acrylic paint (optional)
empty soap bottle (to inject solution into balloons) or basting sirynge
empty plastic bottle (or funnel)
Step 3: Grind Moss
Add the moss slowly into a coffee grinder, or blender if you have one. Grind it slowly, because there will be some small rocks that may damage the blender blade or your eye.
Step 4: Mix Ingredients
Throw the beer, moss, and sugar into a large pot and stir it around.
Step 5: Add Paint and Moss
Now comes the hard part. Cut the top off of a plastic bottle or grab a funnel and attach the mouth of the funnel to a balloon. Now pour your paint into the funnel and fill balloon about half full in it's collapsed state. (we'll inflate it with our mixture next)
Step 6: Pour Moss Mixture Into Balloon
This step is a messy one. Pour the mixture of beer and moss into a plastic soap bottle ( or better yet, a basting syringe). Attach the balloon to this and then squeeze the bottle to fill up the balloon. Watch the balloon as it fills to prevent it from exploding.
Step 7: Inflate
Now i might be best to accept that you probably eat sugar, eat lettuce (moss), and drink beer b/c this step is kind of gross but simple. Just inflate the balloon with your mouth to add more size so that the balloon will pop better when it hits a wall. Then tie of the balloon with an overhand knot.
Step 8: Go Outside
Now just repeat these steps for each balloon, and then go outside and launch them. Hopefully within a few weeks the moss will grow into the shape of the exploded splash with some nice moss drip marks.
( north walls tend to be better spots for moss to grow)
