canning question - why do my jars tip over?

This is my first year canning and so far I've made a few small batches of jam, several batches of pickles, and a batch of salsa. I use a water bath canner.
I was taught to elevate the canner rack (by hooking it onto the side of the canner), place the filled jars on the rack, then lower the rack and jars into the water.
However, every time I put my filled jars into the canner rack, they tip over and end up sideways in the water. I have tried every which way to get them to sit steady on the rack, but no success. Could it be that I just have a really crappy rack? Or is there something I'm doing wrong?
If you suspect the problem lies with the rack, is there another rack you can recommend?
If the jars fall over when you lower the rack, put the rack in the canner and then put in the jars. If they fall over during processing then it sounds like you have a crappy rack. I just have the inexpensive ordinary kind that came from the farm store when I bought my canner in the 80s.
you are not filling the jars full enough. they have too much air and the buoyancy is lifting them out of the holder and allowing them to fall over.
Possibly too much head space, i.e. not filled up enough to keep them from floating? I don't know if this is related or not, but last time I canned some tomatoes several jars exploded during processing. I think it was too LITTLE head space, i.e. overfilled, but could there be another reason?
I've noticed that my jars tip over if the rack is not full- there's too much space in between them to keep them upright. So when I do a batch that's too small for my big canner, I use a smaller pot, and improvise a rack out of the lid screw tops. Seems to do the trick- though not sure if that's your problem.
I have the same problem with pint and half pint jars. I use a typical water bath canner that came with the standard rack inside. The rings of the rack are just spaced too far apart to hold small jars upright properly so I load it with the rack in the water using a jar lifter to place them. They still tilt back against the side of the canner but process just fine. I know they're filled properly so I don't think it's air space. I made a rack out of canning jar rings held together with zip ties for my big Le Creuset dutch oven when I'm doing squat half pint jars in tiny loads. This works great if I'm doing 4-6 little jars as it saves time and energy over heating up the giant water bath.
