The cast of "Jersey Shore" had a blast this weekend as they went soaring on water jet packs -- but one of them had to miss out on the fun.

The Situation, Jwoww, Pauly D, Ronnie, Sammi, Vinny and Snooki were all spotted on a boat in Seaside Heights this weekend, where most of them tried to fly using one of the wild water-powered devices.

And while the whole cast was there, they didn't all join in on the high-flying adventure.

Snooki and Sammi didn't strap themselves into the jet packs, deciding to instead watch as everyone else had a great time.

This should come as no big surprise, as Snooki is pregnant and Sammi never really seems quite as adventurous as her crazy costars.

That being said, those who went for a ride definitely looked like it was something they won't soon forget. Just look at Deena's face!

Check out all the fun photos above.
