Birthday Parties at KiDiMu

Blast Off Into Birthday Fun at KiDiMu! 🧪🔬

Ready to launch an out-of-this-world birthday party?

At KiDiMu, your little scientists, engineers, and creators can explore, experiment, and play in our interactive exhibits while celebrating their special day!

Our customizable party packages let you mix and match hands-on activities, STEAM experiments, and creative adventures to make your celebration truly unforgettable.

After museum hours, our space transforms into the perfect laboratory for private parties, family gatherings, and special events. Our team of “party chemists” will help everything run smoothly so you can enjoy the fun without any extra reactions.

Let’s ignite curiosity, spark imagination, and create a birthday that’s full of smiles, laughter, and a little scientific magic!
