11 AM – 5 PM

On the festival’s final day, COSI and our partners cap off the festival with the explosive Big Science Celebration, Ohio’s biggest interactive science event. The Big Science Celebration is packed full of dynamic science demonstrations and activities led by local STEM professionals, researchers, and experts.

With hundreds of hands-on, interactive science booths from local organizations, communities, universities, and companies, we show off Ohio’s science in the parks and riverfront surrounding COSI. This incredible gathering brings the public face-to-face with STEM experts from academics to pharmaceuticals to zoology— and everything in between. The Big Science Celebration allows exhibitors to showcase to the public how STEM manifests in their daily work and lives in accessible ways – proving that whether in research or banking, engineering or culinary arts, science powers all industries.

The Big Science Celebration is a rain or shine event, please be prepared for the weather. There’s a lot of science in water falling from the sky, so we just view it as part of the incredible experience of the BSC!

In the event of severe weather, stay tuned to our website and social media channels, as well as event staff, for updates.
