All over Robyn

The test tube arced away from Sandry, spilling out purple liquid which splattered on Robyn's trousers, then over her blouse and tie. The cute redhead looked at the chemical soaking into her clothes.

"Is there any chance we made it wrong?" she said hopefully, eyes wide.

"Not with you being a straight-A science nerd." Sandry gulped. "Sorry!"

They could already see the purple liquid turning Robyn's clothes lighter, then holes appearing as the formula began to break down the material. Robyn jumped to her feet as if she was going to be able to wash it off, but it was too late and as she realised this she froze in place, watching her uniform fall to little pieces, dropping from her body like ash.

In a few seconds, she was reduced to nothing but a pair of purple knickers with a picture of Pikachu on the front and the slogan 'gotta catch them all' across the back, an old white vest trimmed with pink lace, and a grey bra underneath.

"My clothes!" Robyn gasped, looking down at the pile around her feet, the remains of her uniform still dissolving and getting smaller.

"I'm so sorry!" Sandry said again, as the class turned to see what was going on. Laughter broke out and Robyn's face turned bright red, she squirmed in place and tried to cover her embarrassing underwear with her hands.
