I pollinated cherry tomatoes on my balcony with a cotton swab for the first time and it's working well!

FYI Tomato flowers are cleistogamous and are 95%+ self-pollinating. So pollen on tomato flowers doesn't actually need to be transfered between flowers. The flowers just need to be shaken up a bit to get the pollen to drop from the anther to the pistil.

So take something that vibrates like a electric toothbrush, massager, or other personal devices (wink, wink) and shake the hell out of the flowers.
