Effervescence Task

Postby Unome » September 3rd, 2018, 7:14 pm

See rule 4.b.iii

Fits the trend of increased specificity in the rules. It's pretty similar to last year's gas expansion task.

Last year's gas expansion task was supposed to be due to a result in increase of temperature not a chemical reaction. The expansion of gas (CO2) of these tablets in water are due mainly to the chemical reaction not due to the increase in temperature. So this is not like last year's gas expansion task but it is similar o last year's chemical reaction to expand a balloon task but without the 20cm requirement and without forcing the use of a balloon.

So how are you guys planning on accomplishing this? We've been stuck for a while... :?

Use a 2 chamber system similar to a barometer, connected by water in between. Have the tablets dropped into one chamber to increase the air pressure in that chamber, which will push water into the other chamber. This could be used for something like raising a golf ball.

Hi everyone,

Is it possible to combine this task with the endothermic task? If you interpret it as the heartburn pill's reaction with water triggering an endothermic reaction, could it count as two separate scorable actions?

That's very iffy. It'd be very hard to demonstrate the difference between the two to an ES. Additionally, you'd have to be sure that the endothermic action triggered the following action as a result in reducing temperature, not the gas produced by the tablet. To be safe, I'd just have an entirely separate action.

That's correct. However, the even bigger rule that is being broken here is that in 4.b. it specifies a "unique" action. You can't use the same action as two different actions. Furthermore, it's impossible to write on your ASL that one action counts as two different actions.

So I have a quick question about it, it says “drop two effervescent heartburn relief tablets into water so the reaction triggers the next action” would it count if you dropped water into a container with 2 effervescent tablets?
Thanks!

I would say no.

When using a barometer system, wouldn't that require some water to start in the chamber with the golf ball? Is this legal? Additionally, would this be considered a unique container which water is being added to or could the supervisor consider the entire contraption a single container?

Yes it would require water to starting with. I see no reason why it wouldn't be legal. The rules just say "add water to a container," not add water to a dry container. And I think that as long as there's a clear division between the two sections (ie a tube connecting the tablet container and the golf ball container) then it's pretty clear that they're separate.

Are we allowed to drop more than 2 heartburn relief tablets into water?

The rules specify two, so I’d say no

I'd presume TheSquaad needed a faster reaction rate, or more gas to be produced.
