The Science Party That 5-Year-Olds Go Absolutely Wild For!
Their first proper birthday party deserves something truly special — not another soft play or party bag full of sugar – something that has them bouncing off the walls with excitement for all the right reasons!
Dear Busy Parent,
Planning a party for a 5-year-old can feel overwhelming. You want it to be magical, memorable, and just right for their age, but finding something that genuinely holds the attention of a room full of excitable 5-year-olds is no small thing. That's exactly what our presenters do, every single weekend, all over England.
We'll let you in on something most party companies won't tell you: at 5, one hour is the perfect length. Our one-hour Gold Party is packed with wow moments – slime, rockets, spectacular experiments – and ends while they're still at peak excitement. The result? A party they'll talk about for weeks, and parents who can actually enjoy the day too!
