Some long weekend fun ....
Here is a riddle for you!!! If you share your ideas and questions here, maybe you can come up with a solution together! Good Luck!

I thought I'd check out our blog, its kind of hard to do this from where I am at the moment but...the only way I can think to split the rootbeer is to fill the five litre jug and then put one litre into the eight litre jug, you'd have to find someway to split it into eighths though. Hard riddle though.
Are there markings on the jugs for every litre
Yes, this is tricky, but you can do it! No, there are no litre markings on any of the jugs, so there is no way of pouring 'part' of a jug and knowing how much that is.
Mmmmmm......
Good Luck!
I know that my solution sounds stupid, but can you drink 6 litres of it and then split the 6 liters left into 2 groups of 3 litres?
Wait! I've got it! No.. lost it.
Wait! I've... Nope. Nevermind.
Hey, Ms Watt, I was wondering if I could request a discussion topic. You see, there's been the huge crisis over Mohawk land in Caledonia. The provincial government has just labelled it a state of emergeny there, and I would know. Yesterday I had to help my extended family evacuate from there. I have lots of information and I think it would be great to discuss everything that has happend there in general, since it is a local topic really (a 1.5 hour topic away.) Just a thought.
Rocking On,
Postman Craig
are you allowed to make marks on the jars??
1) No marks on the jars allowed or necessary!
2) Great idea Craig...can you introduce this tomorrow??
I think that if you fill up the 8 litre jug and pur 5 litres into the 5 litre jug you have 2 litres left in that then pour that in one cup. That is the start of something but I can't figure out the rest
F.Y.I. no cups allowed! Only the 3 jugs.
Come on now....don't give up!
This is a weird brain teaser, but I'm guessing that it has got to do with logic. My brain is kind of bieng pressed with stressful scholl pressure so I can't think right now.
I give UP
I'm pretty sure that the only combonation that would work was if you has 3 liters in the 5 literjug, 8 in the 8 and 1 in the 12. That adds to 12, and if you pour the 8 in the 5 you'll be left with 6 in the 8. How you get that............
Wait...thats not the only combonation........scratch that.
Wait.....mabey it is.....ohhhhhhhhhhhh
I have a great idea! It's kind of like Sapphire's, but more advanced.
First you pure 8L into the 8 litre jug, then you pure 5L from the 8 litre jug to the 5L jug. That will leave 3L in the 8 litre jug. DRINK THAT. Repeat this process again when you pured everything back inside the 12L jug (which will only be a quatre full this time). Then you will get 6L IN YOUR STOMACH and half in the jugs.
P.S. You'll probably have to go pee soon!
Wow! I hope we'll reach the solution soon, but I see something a bit wrong here.... Ms. Watt said that we wouldn't need measuring tapes, and the problem with tweedele-dee's method is that we'd have to measure the amount of liquid inside! For Diamond's solution we don't need to, but it just doesn't sound right.... ecxellent thinking though to all the people who are trying....
Gotta GO!
I got it!!!!!!!
If you don't want to see it don't scroll down!
this is what you do.
1. 12 in 12
2. 12 to 8 (8 in 8, 4 in 12)
3. 8 to 5 (3 in 8, 5 in 5, 4 in 12)
4. 5 to 12 (3 in 8, 0 in 5, 9 in 12)
5. 8 to 5 ( 0 in 8, 3 in 5, 9 in 12)
6. 12 t0 8 (8 in 8, 3 in5 , 1 in 12)
7. 8 to 5 ( 6!!!!!!!in 8, 5 in 5, 1 in 12)
8 5 to 12 (6 in 8, 6 in 12, 0 in 5)
yaaaaaaaaaaaay
WOW! How did you do it?! I just have on question, but I'm not sure if it is stupid or not because my brain is kind of foggy right now, but up to the last few steps everything seemed so perfect, but then, in the 6th step and on, how do you measure how many litres you pour into each one?
Diamond - great thinking - outside the 'jug'!!
....and Tweedle-Dee - a fabulous solution - well explained!!!!!!!
Great work both of you!!!
Are there more solutions??
Possibly shorter???
you pour the jugs until they're entirely full. There is no mesuring, butyou know how much space is in each and how much pop so it works.
Good Thinking Guysh!
You sell the 12- Litre Jug for 12 1-Litre Bottles or 6 2-Litre Bottles. No one said commerce couldn 't be involveed!
I think that was genius thinking by Postman Craig. Yet that isn't the real reponse. Good thinking Tweedle-Dee
OH!!!! I get it! Thanks tweedle-dee! You're amazing!
hi Ms. Watt!!! awesome site! i luv the way we can still keep in contact over the week this way! will this site still be available for conversation over the summer?
I am soooooo glad SOMEONE came up with a valid soulution. I was up fo some later hours trying to sleep in my bed going over the problem over and over-I couldn't get anything. THANKS TWEEDLE-DEE!!!! I'll sleep better tonight:)
Congratulations to all of you who solved this problem either in class or here on the blog.
You'll find this riddle and lots of others at the following site:

Answers are there too, but don't be in too much of a hurry to check them!
Happy riddling!
I think she pours half into the 8 litre jug and keeps pouring half and half into the 8 litre jug and the 12 litre jug until there is exactly half and half in both jugs!! sp,etjomg ;ole that!
