Fill the bottle with water. The ketchup packet should float somewhere in the middle of the bottle. If it sinks, either try using a different packet (the size of the air bubble inside the ketchup packet varies slightly) or else dump out the water and ketchup, bend the packet slightly so that it can hold an air bubble when you fill the bottle again, and refill the bottle. My packet was heavy, so I trapped an air bubble on the packet and tapped the bottle with a fingernail until I knocked off just enough air bubbles to get the packet to sit in the middle of the bottle.
Squeeze the bottle to cause the ketchup packet to sink.
Relax your grip on the bottle to cause the packet to float. With a little practice you can make it appear that you aren't squeezing the bottle. If you are performing this demonstration as a magic trick you can say you are using the power of your mind to move the ketchup. Pretend to be concentrating very hard, using your incredible powers of telekinesis.
