With just one balloon and one crispy pappadam, you and your child can discover the hidden world of sound vibrations—while enjoying a festival snack in a brand-new way.It’s fun, quick (just 5 minutes!), and secretly builds your child’s curiosity about science. What You’ll Need<ul><li>1 medium-sized balloon</li><li>1 crispy pappadam</li></ul><h3 id="e18a492a-561e-4e17-a289-dc5e2011a37b" data-toc-id="e18a492a-561e-4e17-a289-dc5e2011a37b">The Secret Behind the Wow Moment</h3><ol><li>Blow up the balloon to a medium size and tie it securely.</li><li>Gently press the balloon against your child’s ear.</li><li>First, break the pappadam near their other ear—they’ll hear the normal crunch.</li><li>Now, gently touch the pappadam to the balloon and break it again.</li><li>Watch their face light up as they hear a HUGE, amplified CRUNCH—almost like a superpower! </li></ol>Pro Tip: Record their surprised reaction—you’ll want to share this moment! The Science Secret The magic is all about how sound travels! Sound moves in waves of vibrations. When you break the pappadam in the air, these vibrations have to travel through air molecules, which are spread far apart. This makes the sound seem quiet.However, a solid object like a balloon has molecules that are packed very tightly together. When the pappadam breaks while touching the balloon, the powerful vibrations travel instantly and efficiently through the solid balloon directly to the ear. This makes the sound seem much louder and deeper! Stay tuned for Day 2 of TinkerOnam, where another wow moment awaits your family!
