... a bag of toy balloons.
You open the package. There are balloons of all shapes, colours and sizes. Still, you're not sure about what to do with them.
You pick a random balloon and start blowing it.
'Pffft! Hufffff!'
You put some effort into blowing this toy up, so it grows pretty quickly. It's a simple round crystal red balloon. As you inflate it, it turns into more of a pear shape. You stop blowing and tie it up, making squeaky noises of rubbing latex against latex.
You hold the balloon before you, arms outstretched. It's big! Probably twice as big as your head.
You release it and it flies up to the ceiling.
'That's odd. Am I breathing helium now?' — you ask yourself.
You feel a strange, unnatural tension in the air. It's almost as if there are invisible strings everywhere and if you pull one...
You concentrate and make a hand gesture for the balloon to come down. And it does!
You make another gesture and it reshapes into a long, blimp-shaped balloon.
'I wish it was purple' — you think. And the balloon magically turns crystal purple!
You look in the direction of that bag from the box and wish for all of the balloons there to be inflated.
With a loud 'WHOOOSH' balloons blow themselves up, ribbing the bag apart and scattering all over the room, knocking stuff down. A whirlwind of colours, like a carnival~
You try changing the colour of your dress by giving a mental command and it works like a charm. You decide that a blue dress would go well with your new eyes.
'O-okay. I can control latex now. Has to be the lamest superpower ever' — you sigh.
