Turn their Minds against themselves

"Ah GIL Nextdor. What a perfect specimen." Susan coo'd as she checked the cameras outside.

"I still don't get why you guys are so into him." Johnny quipped as he blew another bubble of gum. The boy stood on a testing platform, with a blast shield between him and his sisters. "What's this supposed to do again anyway?" he asked after popping the bubble.

"The mind of a woman is beyond your understanding little brother." Mary answered as she noted the data coming in, "And this is a revamp of one of our gum tests. Double the flavor, double the strength!"

"We're trying to see if we can revamp the construction industry by replacing brick with bubbles that are just as strong. The cost of materials would massively go down and the housing crisis could be solved! Think of it, we'll win..." Susan started in before interrupted by a quesiton from Johnny.

"Couldn't you just blow a big enough bubble for house?"

Susan turned and saw a huge bubble from Johnny, taking up possibly a third of the room. She nervously looked at her twin who was sweating as she checked the data. With a confused look she turned back to her dim witted brother.

"Er... very good Johnny but question. How do you get into the bubble?" the girl asked.

"....Oh right... hahahahah sorry." Johnny offered.

Only for part of the huge bubble to snag a rather sharp piece of machinery and pop. The amount of air let loose sent Johnny flying around the lab, crashing into things and his dog Dukey, and carried the two out of window that Mary quickly opened. The two flew through the air for sometime before crashing into the back yard next door.

"I'm okay!" came Johnny's voice with another voice piping up about "What's happening Johnny brah?" along side him.

"Guess that idea needs more time. Too much pressure on the air inside. Possible dangerous explosive decompression if we were to market it now." Mary noted as she typed out the extra info Johnny's stunt gave them.

"Agreed. But on the bright side we might be able to give, Gil Nextdor, some medical attention." Susan sighed as she got the first kit out.

"Let's just leave the nurse outfits home this time though." Mary replied as the two headed out.

What no one realized was a small little drone that snuck in through the window, and grabbed a number of documents on the table before scurrying away.

It didn't take long for you to have an opening. Either the girl's distraction with Gil, some act from their brother, or some other random event would give your drone a chance to steal some data from the lab. Heck, from your observation, it seemed to be a common occurrence for someone to do this to the pair.

You relished the return of your drone and handed the documents over to your Pawns to translate the words to something you could better understand. They returned with a number of different inventions, mostly failures. The girls were big on trial and error it seemed. Still the two were smarter than you and while you couldn't make a one to one recreation of their inventions, you could get an idea based of them. Put your own spin on the idea to make the twins succumb to your will.
It was just a matter of picking one.
