how well do tea lights float? looking for inexpensive floating candles?

i am looking for cheap floating candles for a wedding and wondering if tea lights will work instead?
any suggestions?

thanks.

The tea lights I’ve seen have a metal cup around the outside of them-I don’t think they will float. But I have found some nice floating candles at the dollar store in quite a variety of colors. Check it out. Congratulations on your wedding,good luck.
