cider activity

I sanitized my cider day before last with campden for 24 hours. I let my yeast sit in like 65-70 degrees for 8 hours to activate (had it in fridge). I mixed my yeast in with like 1/4 cup of luke warm water like package says. Mixed in yeast, threw in some cloves and cinnamon sticks. When should i see activity on the airlock? Most of the water is pushed to one side of airlock, but it doesnt seem to be bubbling, it has been like 8-12 hours. Is this normal? will it pick up in a day or so or do i need to do something to get it going?

Thanks, George
