Celebrate With Science – An Extraordinary Birthday Experience

Are you looking for a birthday party that is as educational as it is fun?

At Mini Professors Den Haag, we specialise in creating joyful memories for curious minds aged 4 to 8 through hands-on discovery and scientific wonder.

The Party Experience

Every science birthday celebration is 2 hours long, providing a balanced mix of structured discovery and social celebration:

  • 1-Hour Science Programme: A captivating session led by a Mini Professors expert. It features 5–6 experiments, including interactive demonstrations (like Elephant's Toothpaste!) and hands-on activities where the children get to be the scientists.

  • 1-Hour Open Celebration & Play: Following the science, the second hour is yours to use as you wish. Children have exclusive access to our "super awesome" toy collection (Lego, K'nex, magnetic tiles, Clics, and more). This is the perfect time for the family to serve snacks and cake, open presents, or enjoy free play.

    • Note: This hour is supervised and managed by the booking family.

  • Easy Setup: Families are welcome to arrive 30 minutes before the party starts to set up cake, snacks, and any personal decorations.

  • Stress-Free Finish: We handle the entire cleanup of the venue and all science materials, so you can focus on the celebration.

Choose Your Scientific Adventure

Our 1-hour science programs are a captivating mix of 5–6 experiments, featuring both interactive demonstrations and hands-on activities where the children lead the way.

Crazy Chemicals

Dive into the world of thrilling chemical reactions. Watch the famous "Elephant’s Toothpaste" erupt, see the classic Cola and Mentos explosion, and experiment with bubbling baking soda and vinegar.

Awesome Air

Discover the invisible power of air through high-energy experiments. We float balls in mid-air, construct paper helicopters to test flight, and even create a swirling tornado in a bottle.

Marvellous Magic

Unveil the real science behind tricks that baffle the mind. Watch as we make paper and water disappear before your eyes. Plus, every child gets to make their own slime to take home!
