Many high schools use butchers' paper for posters of clubs, and upcoming events. It is a cheap but sturdy paper that is sold in large rolls. Butcher paper is usually white or reddish in colour, made from kraft pulp , and is generally considered to have a density of between 30 lb/3000 sq ft (49 g/m 2 ) and 50 lb/3000 sq ft (81 g/m 2 ).
Ricin (/ ˈ r aɪ s ɪ n / RY-sin) is a lectin (a carbohydrate-binding protein) and a highly potent toxin produced in the seeds of the castor oil plant, Ricinus communis.The median lethal dose (LD 50) of ricin for mice is around 22 micrograms per kilogram of body weight via intraperitoneal injection.

Butter may be measured by either weight (1 ⁄ 4 lb) or volume (3 tbsp) or a combination of weight and volume (1 ⁄ 4 lb plus 3 tbsp); it is sold by weight but in packages marked to facilitate common divisions by eye. (As a sub-packaged unit, a stick of butter, at 1 ⁄ 4 lb [113 g], is a de facto measure in the US.)
Taking the standard (but no longer existent) 70kg medical adult, and using the lesser fatal dose of 20mg/kg gives the fatal oral dose to be 1400mg - about 0.6 pounds - of pure ricin. Even if each castor bean is 100% ricin (which seems improbable) then with a fatal dose range of 5-20 beans, each bean must weigh between 0.5 and 2 ounces.
