YEAH, they are fULL of water/sap. Like the guys said, all you can do is dry them. Another trick that may come in handy with these is to use some cheap wire and wrap them tightly to hold them tight as they dry. Keep the winds as close, but not overlapping as possibe. Drilling is almost a must. The vines will shrink some as the water leaves them, so you my have to rewrap them a couple times Good luck,
