After brain storming with Jester, Sammy has decided on a present. He went to Father Benson and requested 4 liters of perpetual ice mix. His gift was an everlasting ice scupture of the king. Unfortunately, when he was gathing water, his pot broke! It was not because he had tripped, yep the clumsy librarian is not that clumsy........Anyways, His pot now holds 3 liters and the spare one holds 5 liters. He needs exactly 4 liters because any more would result in normal ice and any less will supersaturate the water and make it look ugly. How should Sammy fill the pots so he has 4 liters of water.

Note: I know this is from a movie. Luckly, there are 2 answers. I will provide both answers tomorrow.
