1. It’s a Guinness World Records-Style “BIGGIE” Challenge

This month, Kids Invent Stuff is inviting kids aged 4–11 to dream up inventions that could set or smash a Guinness World Record—whether it’s the biggest, the fastest, the tallest or the longest, so long as it’s measurable and fun to watch. Check out the details on Kids Invent Stuff. It’s the perfect way to turn wild ideas into record-breaking reality!

2. What Makes a Winning Idea?

They’re looking for creations that are:

• Easily measured or counted
• Replicable or beatable (so others can try too!)
• Exciting and visually fun—because part of the joy is sharing it with the world!

This guidance helps channel creativity toward ideas that shine on screen—and maybe even in the record books. Learn more on the challenge page.

3. Entry Deadline: 31st July

There’s a clear cut-off for submissions—31st July—so budding inventors should grab the downloadable invention sheet now and start sketching, filming, or building their concept. Find everything you need on Kids Invent Stuff.

4. Experts on the Job: Ruth & Shawn

If your idea is chosen, engineering duo Ruth & Shawn will bring it to life on video. If their build succeeds at breaking a record, it could even end up in the 2027 Guinness World Records book! Check out how it all works on the Kids Invent Stuff challenge page.

5. Incredibly Accessible – For Everyone & Everywhere

This challenge is open to all kids worldwide (ages 4–11), completely free, and generously supported by Accu and the Royal Commission for the Exhibition 1851. It’s a global invitation to spark creativity and STEM fun from anywhere. Learn more at Kids Invent Stuff.
