About our parties

We come to your home, garden or a rented venue of your choice. Our parties last between 1 hour to 1 hour and a half (depending on the theme and whether you choose to add Dry Ice or Cotton Candy.

We require a floor space where the children can sit around the presenter to watch exciting interactive experiment demos. Minimum space needed would be 3m by 3m. We require a table where the children have enough space to stand around an do an experiment of their own. A 180cm table is ideal. 

We bring table protectors and where necessary floor protectors. The parties are safe, exciting and we always clean up to ensure you are not left with a mess. 

We offer our parties at 10:30 and 14:30 on Saturday and Sunday. On request we might be able to offer other days and small time changes to help you. 

We travel to your home from 8926 on the border between Zug and Zurich. We are able to offer our services within a 30 minute google map radius of 8926.

Four of our parties are suitable for ages 5-11. We differentiate the themes slightly to make them suit the age group we have. These parties are Bubbles, Bangs and Burning, Rainbows and Unicorns, Dino Dig and potions Party.

Harry Potter party is suitable for ages 7+ (due to many younger children being unfamiliar with the story)

Subzero Science and Slime Time is offered for children 7+ as the experiments within these parties are unsuitable for smaller children.

Ice Cream Factory is available on request. This party is led in English and not German. This party is suitable for children aged 9 - 14 years.

We've booked Spark Science for our daughter's 5th birthday party. Some of the kids were still 4 but Emma helped us choose the best activity for the grpup. We went for rainbows and unicorns and they made slime. There were boys and girls in the group, most of them just turning 5. They all had a blast and loved Kilowatt Katy. The other parents present were super impressed by how she handled 13 kids for an hour and the children all say they want to do more experiments with her.
Everything was really well organised I couldn't be happier.

We absolutely LOVE Spark Science. The kids have been to all of the camps (some twice) and keep wanting to go back. It is amazing to see how well thought through the programmes are making things super fun for the kids and super informative for them to learn about the world.

We also booked "Bubbles bangs and burning" for our daughter's party and we have been to numerous parties where Emma or Katy performed their science magic nurturing the curiosity in our kids.

Davina B, Feb 2023

If there was a 10 out of 5 stars I would choose it. Spark Science created the most magical party for my 8 year old son. We chose the Harry potter package and every thoughtful and clever detail added to the experience. The costumes, the décor and the imaginary play. They got to create the impossible themselves instead of watching - completely hands on. The science was so interwoven with the story of Harry Potter: Fantasy and learning blended into one fabulous afternoon. Emma had them all transfixed!! Quite a challenge with nearly 20 kids of that age and having to navigate across three languages.

Thank you Emma for going the extra mile (infact the many extra miles) and for working with so much love.
