After the TouchTrix starts, the screen will switch to the start up screen (displaying the large battery icon). When the 'Battery' icon flashes shake your iPhone and the battery icon will charge right up! After the 'Battery' icon flashes again, slide the larger battery icon to the side and an extra battery icon will show up. Shake your iPhone again and charge the extra battery to show you’ve got energy to spare!
Once the Trix starts, tell your friends there’s been a new breakthrough in iPhone battery technology using “Shake Technology”. If your act is good enough, you might just be able to make believers out of them.
