You need:
6 Elastic Bands
1 Wii-mote
1 Badminton / Tennis racquet

I wouldn’t recommend you getting a new racquet for this, a spoiled one would do. Remember to tie the wii mote tight so that you won’t smash your plasma screen by ‘flying’ away your wiimote.

Sometimes you might have difficulty finding your wiimote and nunchuck controller. They may just be anywhere around your house, such as behind your television, in the cupboard, kitchen, on your bed, table, and don’t be surprise, they might even inside your sofa.
Brando is now selling Wii WeDock which cost USD 19.00 for you to store two sets of wiimote and nunchuck controller in a cool box (both black and white are available). Something got me when I was browsing the product, $19 for a box for two sets of controller? What if I have four wiimote and nunchuck controller? (Nintendo Wii is a party game) It’s no where helpful for those who are already unorganized (throwing your controllers everywhere).

You can actually play nintendo wii without television. The Japanese came out with this portable LCD wii product, just bring it around and plug in your wii, you can play anywhere anytime (provided there is power supply). When i saw this, what came into my mind was that it a larger version of GameBoy.
