Salford University are opening their doors to local families this weekend to show off boundary-breaking experiments in the world of science.
It's the 10th anniversary of the Manchester Science Festival.
So Salford gets a big roster of hands-on free events to look at the latest developments in science, technology and what top boffins are doing to expand human knowledge.
At MediaCityUK on Saturday 22 and Sunday 23 October, 10am – 4pm, you can learn how to build Lego 'robots' and bring them to life using simple software.
Dress as your favourite superhero and get transported to another world – using the green screen technology in BBC TV studios.
Also on the bill are neuroscientist Di Mainstone, who has set up The Sensory Sound Pit – a tactile experiment to show off all the ways the brain responds to sound.
And there's the 'Forest of Curiosity', opening up the science of the forest, from insect and animal behaviour to the post-apocalyptic world of Chernobyl's radioactive wilderness.
There's stuff going on all across Manchester and Salford from Thursday 20 October to Sunday 30 October 2016.
