NO QUESTION TOO SMALL

QUICK QUESTIONS, HONEST ANSWERS

The five things every parent asks before the missions begin.

What age is it for?

Ages 7–12 is the sweet spot. Confident 6-year-olds love it with a grown-up reading along, and plenty of 13-year-olds “just check something” and keep going. The comic format means reluctant readers and bookworms both finish it.

How long is shipping?

Orders leave us within 24 hours and arrive in 2–5 business days, fully tracked. You’ll get a tracking link the moment your books are on their way — kids LOVE watching the parcel get closer.

What if my kid doesn’t like it?

Then we refund you. Every order is covered by our 30-Day Giggle-Proof Guarantee: if your child isn’t into it, email us within 30 days for a full refund — no questions, no return shipping, no hard feelings.

Are the experiments safe?

Yes. All 16 experiments use kitchen staples — balloons, baking soda, old CDs, string — and each one carries a clear “grown-up level” label. Most need only light adult supervision, like handling scissors or warm water.

Is there a bundle?

Yes! Grab both books together — Gravity Gang and Fizz Force — and save. Physics first, chemistry second, or the other way round: the missions work in any order, and the certificate wall looks twice as impressive.
