Ever wondered how to use ketchup to clean coppers, make mini explosions, or create your own sunset? CHaOS’s interactive Experiment File Workshops are here to show you how! Complete two weird and wonderful experiments in real time along with our friendly student volunteers, learning loads of cool science along the way! 

These workshops will take place over Zoom. You will be allocated a virtual room, where our student volunteers will guide you through two different experiments per session that you can do at home with household objects. In each room a different pair of experiments will be demonstrated - see the below description for which pairs you can choose from. Please note that you will need to provide your own materials for the experiments, but these are all widely available. Details of the required materials will be sent out after booking a ticket, but these can also be found by viewing the relevant Experiment File - follow the link below!

Each session will cover two files - upon booking, we will ask you which experiments you would like to do. These pairings are random! Choose from:

  • Oil and Pyrex & Cornflour
  • Red Cabbage & Celery Food Colouring
  • Sunset Model & Hearing High Sounds
  • Mini Explosions & Cleaning Coppers

For details on the experiments, check out our Experiment Files here

Our experiment files are available on demand, but our Workshops are at specific times!

Booking is required for the event. We ask that you familiarise yourself with our Code of Conduct for virtual events. Children must be accompanied by an adult when attending any online CHaOS event. When booking your ticket, ensure you use the same email address you intend to use to join the Zoom meeting!
