Grab Your Lab Coat & Goggles, The New Guinness World Records Science & Stuff Book is Here

Grab the new Guinness World Records Science & Stuff book – the grossest, smelliest, weirdest and noisiest guide to, well, science, and join Ivy and me in making the marshmallow catapult and attempt to break a Guinness World Records title!

In the Make & Break chapter, there are 10 experiments that can be used for official Guinness World Records title attempts at home.

You can learn how to make your own lemon batteries, a homemade marshmallow catapult like we did, or even a Mentos and soda rocket car. There are 10 Make & Break experiments.


The book is full of very cool and fun facts, like how 1.3 million copies of the book You Can Do the Cube by 13-year-old wrote in 1981 about solving the Rubik’s Cube were sold. The current Guinness World Records title for fastest 3x3x3 solve of the Rubik’s Cube is held by 15-year-old Patrick Ponce from September 2017 with 17 turns in 4.69 seconds. Woah.

Did you know that Usain Bolt, of Jamaica, is the World’s Fastest Man? Bolt holds the Guinness World Records title for the fastest 100m at 9.58 seconds, the fastest 200 m at 19.19 seconds and helped set the team Guinness World Records title for the fastest team for the 4×100 relay at 36.84 seconds!

This book is the ultimate resource for your budding scientist.

Now, let’s dive into our ‘Make & Break’!

Although I know we didn’t break any Guinness World Records titles, I enlisted my hubby, an engineer to construct the catapult with us, and Ivy enjoyed her share of marshmallows in the process!

What We Used to Build Our Catapult:

  • 2.5cm x 2.5cm (minimum size) marshmallows
  • Bulldog clip
  • Bottle cap
  • Wood lollipop sticks in two sizes
  • Hot glue gun
  • Scissors


In order to submit for a Guinness World Records title attempt, you will need to:

  1. Submit details and diagrams of your proposed catapult design to Guinness World Records for approval before you make the catapult.
  2. The marshmallows can be square or round in shape but must be 2.5cm (1in) in all dimensions.
  3. The person catching the marshmallows (by mouth) must be standing at least 2m from the catapult at all times.
  4. Only one marshmallow can be fired at a time. (It’s up to the challenger whether they eat or spit them out once they have been caught in the mouth).

The book gave us step-by-step instructions on how to build a catapult for fun!


I enlisted hubby’s help because he’s the engineer, and I’m SO NOT.

Ivy’s completed marshmallow catapult! We had too much fun with this part!

The Guinness World Records book, Science & Stuff, can found at Amazon, Indigo, and McNally Robinson and is only $18.99 Canadian (Suggested Retail Price).

Time to put your lab coat and goggles on because this book is a must-have for all members of the family.

It’s important to remember that setting or breaking a Guinness World Records title is never easy, so be prepared for things to not always work. If at first, you don’t succeed, look for some inspiration then try again!
