Fragile little ones

I'm growing some chinese celery in a pot. A bunch of seedlings have shown their faces and said their first "Hello world!" with great enthusiasm, but they still look oh-so-fragile! Every morning when I water them I have to be very careful not to break or uproot anything. Not that they have real roots yet, but you know what I mean. :)

I'm using a simple IKEA watering can, but is there a better way to water fragile seedlings? I've seen some garden hose accessories that can spray ultra-fine mist, but that's not applicable for me since it'll get the floor all wet.

Here a pic of the little ones in my germinating pot:



The sligthly more grown up guy on the top left is another chinese celery experiment I started a couple of weeks earlier. Is it natural for these guys to grow so slowly? I haven't seen any change in this one for quite a few days now... .
