Kid and parent showing cardboard robotic hand, balloon car and hydraulic crane
Sound familiar?

"Five more minutes…" every single day

😩 Without the Lab

  • You say "turn it off" ten times a day
  • New toys last ten minutes
  • Taking the tablet away always ends in tears
  • Pinterest crafts need a shopping trip first

🤩 With the Lab

  • They have a build to finish, so the screen waits
  • 150 builds: there's always a new one to try
  • You don't ban anything, you offer something better
  • Cardboard, caps, straws: things you already have

What they watch on a screen, they forget in five minutes.
What they build with their own hands, they show everyone.

Why kids keep going

Build · Understand · Invent

Other books give a list of crafts. Every page of the Lab turns a build into a little engineering lesson — without feeling like homework.

1 · Build 🛠️Six picture steps and the exact materials. Your kid can follow the pictures; you just help with sharp cuts.
2 · Understand 💡"How it works" explains the real science: Newton's laws, hydraulics, levers, light, sound.
3 · Invent 🚀The "Inventor challenge" asks them to change one thing and make it their own. That's where the magic happens.

Questions

What ages is it for?

Kids 4 to 12. Every build shows the age, time and level (Easy, Medium, Challenge), and the Parent Quick-Start Guide tells you where to start for each age.

Do I need to buy materials?

Almost never. Most builds use cardboard boxes, paper rolls, bottle caps, straws, tape and string. The few that use syringes or a balloon list them clearly.

Is this a physical kit?

No. It's a digital download (PDF). You get it by email right after paying and can read it on a phone or tablet, or print the pages you need.

Won't this be more screen time?

You look at the step on your phone or print it. Your kid's hands are on cardboard, not on a screen.

Is it safe?

Steps that need sharp cuts, hot glue or poking holes are marked for an adult. No fire, no chemicals.

How do I get it?

Right after checkout you'll see a download page and get an email with your access. Lost the email? Write to us and we resend it.
