"All these Science Spheres are made of asbestos by the way, keeps out the rats. Let us know if you feel a shortness of breath, a persistent dry cough, or your heart stopping. Because that's not part of the test, that's asbestos. Good news is the lab boys say the symptoms of asbestos poisoning show a median latency of 44.6 years, so if you're thirty or older you're laughing. Worst case scenario you miss out on a few rounds of Canasta, plus you've forwarded the cause of science by three centuries. I punch those numbers into my calculator, it makes a happy face."
