Use a small piece of pottery or a bowl to amplify the sound produced by your smartphone. You can create a quick speaker on your desk at work or in your living room at home by simply placing your smartphone (speaker side down) in a container made of ceramic, plastic or other hard material.
The sound will bounce off of the hard bottom surface and amplify it throughout the surrounding area. It’s great for watching videos without headphones or playing music when hosting a party.
