**The Case of the Crazy Canadian Script: **  written by: Dylan Jones

Tom Timmons- Lead Chemist/ Lead Field agent Rick Rogers- Field agent  Tanya Thompson- Field agent  Olivia Moore- base chemist  Tony Gonzalez- base chemist  Mike Bell- Detective


 * Timmons- ** We have just received news from firemen that there were bodies recovered at a house that they were called to.


 * Rogers- ** Where did this take place?


 * Timmons- ** It took place in the suburbs of the Hills.


 * Thompson- ** So its fair to say this was a pretty wealthy family


 * Timmons- ** Yes Thompson you can say that. We want you to ask the neighbors if they knew if anyone who would want to hurt the Bay family.


 * Thompson- ** You got it sir

**Timmons-** We do know that the Bay family owned a Canadian Propane Tank Company. And we need to find out if the there was a defect in the metal of the tank or if the explosion was caused by the heater. The labeling on the tank claimed that the maximum pressure of the tank was 29 psi.


 * Rogers-** Okay so that’s why we were called... because you would think that someone who owns a propane tank company would know how to handle them.


 * Timmons-** Exactly, we have also found that it was one of their own tanks so Rogers you will be going to the company to interview the employees and also find out the exact maximum pressure that these propane tanks can take.


 * Rogers-** Who’s in charge of determining the maximum pressure of the propane tanks in the company?


 * Timmons-** A man named Erik Molanson. He’s been hoping to become CEO because he’s been in the company for 15 years, but the Bay family never promoted him.


 * Rogers-** That could be a clear motive for him to want to kill them in order to gain control of the company.


 * Thompson-** Yeah, I just received word from a neighbor across the street and they always noticed hostility whenever Molanson would leave the Bay’s house.


 * Timmons-** Okay first, we need to prove that the label was false advertising. So make sure you calculate exactly at what pressure did this tank explode.


 * Rogers-** Sure thing, but I’ll need to know some details of the case. Olivia?


 * Moore-** The tank was a Worthington 20lb Propane Cylinder and had the dimensions of a height of 61.595 cm and a radius of 15.39875 cm. Inside the tank, it was occupied by 100 grams of propane (C3H8).


 * Gonzalez-** Also, the tank had an internal temperature of 273.15 degrees Kelvin. And of course the maximum pressure was supposedly 29 p.s.i.


 * Moore-** I checked the heater and the maximum temperature it went up to was 300 degrees Celsius, and we’re sure that the heater was left on so that it reached its max temperature while in the garage.


 * Moore-** Erik Molanson knew that if the tank passed its max pressure it would explode and would not be salvaged at all.


 * Rodgers-** So we are looking for an experienced chemist who has worked with propane tanks?


 * Moore-** Well technically they don’t really need to know that much about propane tanks but yes we are definitely looking for a experienced chemist.


 * Thompson-** And let me guess that Erik Molanson has a background of knowledge of chemistry.


 * Timmons-** Not only a knowledge but a degree!

** Problem: ** //Find out if the tank exceeded its maximum pressure due to the temperature. Prove that Erik Molanson falsely labeled the tank ultimately stopping this crazy Canadian once and for all!//
 * Thompson-** Okay we need to prove this guy guilty before anybody else gets hurt by this possible false labeling.
