You'd like to see a tree grow and prosper, but you don't have a green thumb? Then the beer tree is the right thing for you! You just need to be thirsty, because with every bottled beer your tree will grow a little bit. Hence, the beer tree turns every beer lover into a gardener. The super strong magnet on the top of the tree trunk can easily hold 50 bottle caps if you work on it even up to 70. The more you add, the more impressive the treetop will be.
