W boson

The Particle Zoo


As the carrier particle of the weak nuclear force, the big and heavy W BOSON is downright obese. Not just heavy, it's also two-faced. It is priced a little higher, but it's like getting two particles in one because the front is blue and the back is green and each contains a little sewn-on nametag. W Boson is also part of the Boson 5-pack.

W Boson is a heavyweight particle plush but also comes in a lightweight shipping saver version which is especially nice if you live outside the U.S. So if you prefer it to be filled with lightweight stuffing, just choose that option at checkout and it will only weigh in at 3 oz. Of course you won't get the full effect of its W Boson massive weightiness but it will be the same in every other way.

Approximately 16 oz (0.4 kg); 5 inches (12 cm) across.
For ages 5 and up as it contains glued-on/small parts.
