Save Earth Idea – Recycling Arcade Game!

recycling-game

Call me a gambler but I think the world would have much more incentive to recycle if we had more of these recycling arcade games in every block of every city in the world.

Even better, I’d say legalize gambling legal just for these recycling arcade games except that you can only use recyclable bottles and cans as money.  (but win money if you hit jackpot)

Bug DIY – How to Make a Fruit Fly Trap!

easy-fruit-fly-trap

Fruit flies are common all over the world.  Of course, you will need to learn how to deal with them so you can get rid of them.

One of the best ways is actually to leave your unfinished wine glass (with wine) where the fruit flies are.  I find this method the most effective but my girlfriend told me that the fruit flies will suffer while “drowning” in the wine.  Which is true and perhaps inhumane so I stopped doing that.
