Birthday Parties. Down to a Science!

We're moving!

Lost our lease... Well, actually the proposed rent is no longer affordable. We're not moving too far but until we get all settled we will no longer be able to offer birthday parties in our lab. We hope to have a new and improved lab before the end of the summer. Stay tuned!

Want an unforgettable birthday? 
You’ve come to the right place!

We love sharing our passion for science with kids through our fun, hands-on birthday parties. A science themed birthday party is a great way to entertain kids while sharing the wonders of science... Call it, edutainment. 


"Our Mad Science Party was a huge success and I'm so happy we chose you to host our daughter's 7th birthday party... highly educative and scientific but yet so interactive and fun." -- Michelle, Bellevue


Our birthday parties are:

  • Approximately 60 minutes of non-stop science fun
  • Perfect for girls or boys from 5-12 years old
  • Appropriate for groups of any size
  • Held at your house or other location or our Mad Science Labratory
  • No mess and hassle free!

We offer unique themes that explore science from different perspectives. Your child and their guests will join a genuine Mad Scientist in spectacular experiments and demonstrations! 

We can come to your house or another location of your choice or schedule your party at our Mad Science Laboratory in Bellevue.
