How do I wean bottle-fed kittens to drink water from a saucer?

They're definitely old enough! (10 weeks). They eat only can or dry food, and drink only water, but they've been drinking it out of a bottle, but our last bottle nipple just broke, so they NEED to drink from the saucer, which they refuse to do. Its a bit of a long drive to the nearest pet store to buy a bottle, and we don't exactly have any money to spare on that either, so how do I get them to just drink off a plate, or out of a bowl?
