The business world can be tricky, but for 12-year-old Sienna it’s been downright slimy.

The Derrimut student was browsing the internet one night and came across a video that started her journey.

“I saw a YouTube video of people playing with slime, so I started making it too,” she said.

“I love making it because it’s so fun to play with.”

Sienna sold one or two tubs of slime early on and turned it into a business Slime By Sienna.

“I sold one or two, so my mum made me an Instagram page and Etsy shop to sell it and it grew to selling 300 a week.”

“I’ve sold a few to VCE students who wanted it for stress release and I’ve also been invited to the Royal Melbourne Show.

“I want to sell a lot of slime there.”

Slime By Sienna now has more than 2600 Instagram followers and with such a following, the young entrepreneur has been working hard on inventing new creations.

“I love making different colours and adding all different things in,” she said.

“My favourite is the clear one because you can see your finger go through it.”

Not many 12-year-olds run a business, but Sienna says she goes by a simple motto.

“Nothing’s stopping me from dreaming big.”
