The Particle Zoo
Does this guy look like he's into annihilation? Be careful when ordering this little piece of antimatter–he's likely to explode on contact. One very positive thing about the POSITRON is his work in PET – Positron Emission Tomography, used to detect disease in the body.
Approximately 2 oz (57 gm); 4 inches (10 cm) across.
For ages 5 and up as it contains glued-on/small parts.
