Guinness World Records' brand new book, Science & Stuff, has officially hit stands and features the grossest, smelliest, weirdest, and noisiest records in the world.

In this read, we take a microscopic look at record-breaking across physics, biology, astronomy, chemistry, and more - but perhaps the one of the highlights is the 10 record-breaking experiments you can try at home!

Located in our Make & Break chapter, science lovers can try everything from creating homemade slime to building LEGO bridges.

The best part? All supplies are household objects, and once you’ve completed an experiment as instructed by Professor Burnaby Q Orbax and his assistant, Sweet Pepper Klopek, you can apply for the correlating record!

Our first experiment is the marshmallow catapult, where you’ll need good aim and a reliable laboratory assistant to complete this tasty task successfully.

This challenge requires you to construct your own catapult out of everyday items such as ice lolly (popsicle) sticks and bulldog clips, then use it to hurl marshmallows at a friend (or enemy!).

To begin, gather the household items you see in the image below. Then get to work on assembling the catapult.

For the full break down, head over to our Make & Break page for the full instructions.

Need more visuals? You can see a preview on how to create it with science experts Professor Orbax and Sweet Pepper Klopek in the video below.

If you’ve mastered the art of engineering the catapult and want to take your incredible science work a step further, try breaking a record with your new device!

Simply read the guidelines in the downloadable PDF, so you and a friend can properly attempt the title: Most marshmallows caught in the mouth with a home-made catapult in one minute.

Don’t forget to apply here first, so you can be recognised if you break the record.

This first experiment is one of many coming your way, so stay tuned for our next reveal.

If you can’t get enough of the world’s most amazing scientific phenomenons, be sure to get your copy of Science & Stuff, now available in the US, Canada and Australia.
