After dinner John had just the idea he wanted, and left to grab some stuff from the grocery store. It didn't take him too long, and when he got back he went straight to the kitchen. His father Stew walked by the little experimenter and saw a large mess in the kitchen with a lot of fruit pulp and juices everywhere. Stew said "Your mom's not going to be happy with this..." John willed the kitchen clean and brought out 2 jars of what looked like some sort of juice that looked cold. Condensation was dripping off the jars.
John said "I figured I'd try this out." then handed one of the jars to his father and said "Can you give this one to mom and tell me how they turned out?"
Stew took the other jar of what seemed like Juice and asked "How'd you get these so cold?"
John said "Enchanted the jar, the contents are constantly chilled and I made it so no air could get inside that wasn't in the juice so no oxidation."
Stew said "I'd just sell the jars, but sure I'll see how the drink tastes."
Stew brought the juice jars to their bedroom and entering said "John brought us a prototype for his business. Seems like he's thinking either magically enchanted cups and dishes... or juice."
His wife Erin said "I'll take the green one, and see how badly he made the juice." Stew hesitated for a second remembering John saying something about giving a specific one to his wife, but he handed over the green juice. He forgot which one was for who anyways, and bigger point it was just juice. What was the worst that could happen?" Erin opened the jar of green juice, and Stew opened his jar of red juice. The two started drinking and Stew found it tasted of apples and watermelons and it was refreshing and delicious. He just couldn't stop himself from chugging the whole thing till it was empty.
Stew looked at the jar which seemed completely clean and said "Wow... people are going to be in love with the jars." then noticed Erin had finished her jar of green juice as well."
Erin said "Looks more or less spotless, and while I wouldn't call it good the boy did a good job balancing the vegetables with some fruit." However the more pressing thing for both of them was their stomachs were starting to rumble.
Stew muttered out loud "Were those the right juices?"
Erin asked "What?!?"
Stew said "John said give one of them to you... I didn't think it mattered." Did it matter though?
