Sides of the tube being slippery would just cause a blob of ketchup to come out; worse case, if it was a hard cylinder with no inward facing lip and a release in the for the vacuum created by the ketchup in the tube, all of the ketchup would just fall out in the space of the cylinder.
Key to getting ketchup out is knowing it is a non-newtonian fluid:

Specifically, it's shearing thinning:

Few options are:
(1) Shake it a lot first, then pour;
(2) Jolt the bottle with a hard bump, then pour;
(3) Give it a little time in a single direction to get moving with the pouring end open and downward facing.
- seanp2k2 10y agoMy favorite method is centrifugal; hold the bottle by the non-pouring end with the cap firmly tightened and give it a good fast swing with your arm (be careful not to break it on anything). This will move all the ketchup to the neck of the bottle (might require a few reps). Then, unscrew, and holding the bottle where you wish to dispense product, using your palm just above where your palm meets your wrist, tap firmly on the neck of the bottle just below (as the bottle is now facing downward, just slightly towards the open end) the curve onto the neck while shaking the bottle up and down, with an exaggerated downward "stabbing" motion.
- Declanomous 10y agoI did something similarly clever when I was about 10. My parents still occasionally find a ketchup stain in some far corner of the kitchen or attached den.
