Well I don't think that this is really a tourist trap but I wanted to put it here. There is a small hole cut in the window where you stick your arm and your can toss rolled up paper money into Buddhas hands. It is quite difficult to do. I tried twice and missed both times and son tried too. The little building is full of money. It is a great way for the temple to get donations as it's kind of fun to try.
Here is Hadji trying for some extra luck my having his money land in Buddhas hand but his money also fell to the floor.
