An invisibility formula

Hateya pulls out a crate full of small test tubes filled with a silvery vial and capped with a red cap. "Can anyone guess what this is?"

"A new soda?" Denise asks.

"No," Olivia says. "It is a formula that can grant the drinker the ability to turn transparent after consumption!"

"It's a what?" Monica asks.

"I think she's saying it's an invisibility potion!" Tammy says.

"Well, we don't like the term 'potion,'" Olivia says. "That's the Witch Sisterhood's business. We do scientific breakthroughs, not magic."

"That's not a no!" Chris says excitedly. "This is so cool! I always wanted to turn invisible!"

Hateya nods excitedly. "I'm sure many people have. And what better way to liven up a party or pull some fun pranks by being unseen? Olivia and I came up with the idea after we wanted to sneak away from class to see Sam."

You blush as she continues. "So, we figure these formulas would allow people to add some enjoyment to their lives. If someone wants to sneak out of work, slip into a movie, or liven up a party, they can buy these from us at a modest price!"

"All potential buyers will be screened, and no deals will be made with the military," Olivia added. "We're not making weapons here."

"Wait, can't Jennifer from the Night School turn invisible too?" Nebula asks.

"Indeed," Hateya says. "She was kind enough to give us a sample of her skin to test. We scanned its properties and used it to make this formula."

"That sounds...ick," Rebecca says.

"Oh, grow up," Madison snaps. "We eat worse stuff in the lunchroom."

"I heard that!" Carol shouts.

Hateya uncaps one of the vials and holds it out to you and your girlfriends. "Now, before we finalize the results, we want to test the effects of the formula and make sure it works."

A few hands at the front reach for the test tube, but some of them suddenly draw back. "Uh, wait, doesn't Jennifer have to be...you know...naked?" Alice asks.

"And doesn't it wear off?" Darien adds. "Like, at the worst possible moments?"

"Uh, pretty sure we've all seen each other naked at this point," Brittany says to her sister.

"Yeah, but not during the middle of school!" Darien says.

Hateya and Olivia glance at each other before the science teacher holds out her own test tube. "Alright, then. Whatever our feelings towards possible nudity, we need to test this formula. This is the best and quickest way for us to get a small fortune fast enough to keep our family together."

"We have enough for everybody, including the Night School ladies when they appear," Hateya says. "But we need someone to see if it works. So, is anyone brave enough? Or can we all do this together?"

The two scientists hold out their own vials, waiting for someone to step forward.
