Science Bros! The Adventures of Tony and Bruce

Electron Manipulator

It was a normal day at Stark Tower. The sun was shining, the birds were singing, and everything was peaceful. Bruce walked down the stairs to Tony's work room and pulled open the glass door. He was met with AC/DC blaring through the speakers to the point where he couldn't hear himself think. Tony was fiddling with a little device on his work table with a screwdriver.
"Damn it!" Tony cried out as the device made a loud popping sound and let off a small eletric shock. He shook his hand rapidly as if that would magically make the pain disappear. Bruce laughed and Tony turned his head at the sudden new noise.
"You didn't calibrate the hydro core correctly," Bruce stated, taking the small device in his hand. It was about the size of his palm and was cube shaped, sliver, and had different colored wires attactched to it.
"It's an electron manipulator right?"
Tony nodded.
"Yeah that's right, I was gonna use it on my new suit."
"Nice, but like I said you didn't calibrate the hydro core right."
"Care to explain?" Tony asked gesturing to the little device and his table of tools. Bruce grabbed the screwdriver Tony was just holding and poked at some of the nuts and bolts. He continued to poke at wires and metal as Tont watched curiously. After a few minutes Bruce smiled.
"There we go!"
"I get what I did wrong," Tony said sheepishly, rubbing the back of his neck. Bruce handed Tony the electron manipulator.
"Try it now." Tony pressed a few buttons and the machined whirred to life and lit up. It hummed gently and emanated a soft blue light. Tony gave Bruce a small smile.
"Thank you."
"Anytime."

AN// I honestly just had writers block, I don't know what the hell am electron manipulator or a hydro core is by the way, I just made it up. Please give me suggestions.
