To make to bullet go through the portals straight enough for it to not veer off course and be a problem, you'd have to be extremely accurate, and fast, cos when shooting, you're essentially aiming at the back of your head.Tspoon said:I would create a trap
Put a Portal onto the ground, another in the ceiling,and then drop a knife through.
I would also put one in-between walls, and then shoot a bullet through.
I would then be the first person to watch a bullet die off
