The sneaky science collection: the hydrogen atom pendant.
Contains one proton (geometric silver bead) and one neutron (square hematite bead) housed in the nucleus. It also has an electron on one of three outer orbitals. The electron will move up and down the orbital with energy given by you! :)
Each pendant is hung on adjustable, black hemp cording. Pull the knots together for a longer length and vice versa.
The wire is 99.9% copper with a 0.1% non-tarnish coating to keep it pristine in color for years.
Size Details: 1in high x 1in long x 1in depth
