In 2006, the pop culture publication Radar Magazine called the lab set one of "the 10 most dangerous toys of all time, ... exclud[ing] BB guns, slingshots, throwing stars, and anything else actually intended to inflict harm", because of the radioactive material it included (it was number 2 on the list; number 1 was lawn darts).[14][15][16]
