medicine riddle?

Question

A mother has three sick children. She has a 24-ounce bottle of medicine and needs to give each child eight ounces of the medicine. She is unable to get to the store and has only three clean containers, which measure 5, 11 and 13 ounces. The electricity is out and she has no way of heating water to wash the containers and doesn't want to spread germs. How can she divide the medicine to give each child an equal portion without having any two children drink from the same container?

you can't measure any other measurement besides the full amount of each measuring device

Answer 1

Say:
Bottle (24oz.)
A=Container measure 13oz.
B=Container measure 11oz.
C=Container measure 5oz.
Initially:
Bottle=24; A=0; B=0; C=0

Fills A to rim:
Bottle=11; A=13; B=0; C=0
From A, she fills C:
Bottle=11; A=8; B=0; C=5
Empties C in B:
Bottle=11; A=8; B=5; C=0
From A, she fills C:
Bottle=11; A=3; B=5; C=5
Pours A over B:
Bottle=11; A=0; B=8; C=5
She gives B to child#1.

She's left with:
Bottle=11; A=0; C=5
Returns content of C to Bottle:
Bottle=16; A=0; C=0
Fills A to rim:
Bottle=3; A=13; C=0
From A, she fills C:
Bottle=3; A=8; C=5
She gives A to child#2.

She's left with:
Bottle=3; C=5
Returns content of C to Bottle:
Bottle=8; C=0
She gives Bottle to child#3.

Answer 2

Fill the 5 and the 11. What remains in the 24 is 8 ounces. Pour the 5 into the 13. Use the 11 to completely fill the 13. from the 13, fill the 5. What remains in the 13 is 8 ounces. Pour the 5 into the 11. There's 8 ounces in the 11. Have the children drink from the 11, 13 and 24 ounce containers.

Answer 3

She puts 8 ounces in the 13-ounce, and gives one child the medicine, then puts 11 ounces in the 11-ounce bottle, and gives another child the 8-ounces of medicine, then puts the last 5-ounces in the 5-ounce, and gives the last child 5-ounces of medicine, then opens the 11-ounce container, pours the last 3-ounces in the 5-ounce container, and gives the last child the last 3-ounces, without spreading any germs. I hope this is right! :]
I'm editing then. You put 13-ounces in the thirteen ounce, 11-ounces in the 11-ounce, give them each their 8-ounces, pour the remaining five, in the five ounces, then give the last child that, then the last three, since its not measuring, its just the last of the medicine, in the f-ounce, and give it to the last child. Is that right? :]

Answer 4

its not so clear. first yu say that ther are 3 clean containers and then theres no water to clean the containers..
so can you use those 3 containers?

if so use 11 and 13 containers to put 8 oz in each and give 2 children and let the other child drink from the bottle.

Answer 5

She pours 8 ounces of medicine into the 13 ounce container, 8 ounces in the 11 ounce container, 5 ounce in the 5 ounce container, then refill to 3 ounces and gets the child to drink again out of their 5 ounce container.???????????????
