It seems quaint having an ice festival this year, considering how mild the winter has been.

Actually, let’s think about it this way: the relatively warm temperatures make the whole idea of ice that much more exotic.

With that in mind, you might want to take in the ice sculpture demonstrations and all the other winter activities at the Ice Festival Saturday through Monday (Monday being Presidents’ Day) at the Mystic Seaport Museum.

There is a sock-skating rink for children, or they can indulge in some toy boat building. Folks can gather round a fire pit and nibble on s’mores.

A new feature for this annual festival is a piano performance by Canadian musician Roman Zavada, set to a 360-degree video of the Northern Lights projected on the Planetarium dome. It’s called “Resonances Boreales,” and the half-hour concerts will being at 1 and 3 p.m. each day. Tickets are $3 for members and $5 for non-members and can be purchased at the Planetarium starting at 10 a.m. on the day of the show.

(There are also after-hour, 60-minute performances at 7 p.m. Friday through Sunday, and tickets are $8 for members and $10 for non-members.)

The ice sculpture demos, by the way, are held Sunday and Monday.

Ice Festival, 10 a.m.-4 p.m., Saturday-Monday, Mystic Seaport Museum, 75 Greenmanville Ave., Mystic; $19 for ages 18 and up, $16 for ages 4-17, free for kids 3 and younger; (860) 572-0711, www.mysticseaport.org/icefestival.
