The Particle Zoo
Has the TOP QUARK yielded to the obesity epidemic? We may never know because it only exists for .4 million million million millionths of a second. Top Quark makes all the other particles in the zoo feel quite slim. It is part of the Quark 6-pack.
Top Quark 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 2 oz. Of course you won't get the full effect of its Top Quark massive weightiness but it will be the same in every other way.
Approximately 14 oz (397 gm); 5 inches (12 cm) across.
For ages 5 and up as it contains glued-on/small parts.
