I sense that you could use a television.
TVs like these Hisense TVs are great for looking at. But that's not all! No they can engage all of the other senses too! Check it out:
Hearing: Many televisions, like these Hisense ones, have speakers in them, so you can hear them too! Imagine that! You could CLOSE YOUR EYES and STILL KNOW THERE WAS A TELEVISION IN THE ROOM! Ridiculous!
Touch: Since remotes were invented, not many people touch televisions. But that doesn't mean you can't if you want to! Seriously, go touch your television. How would you describe it's texture? Television-y? Or not so television-y? If you answered not-so-television-y, make sure you're actually touching a television and not a fish tank.
Smell: Have you ever smelled a television? It might smell great! Like fresh-baked snickerdoodle cookies! Or penne a la vodka! (It probably doesn't, but you won't know until you've tried it!)
Taste: How do you taste a television? Well, first of all, you don't want to eat the whole thing all in one sitting. In fact, don't eat it at all. Just lick it. Slowly. Taste the plastic part and the screen part. Does it taste different when different shows are on? Is it sweet or savory? If you wanted to impress your friends with your cooking skills, would you bake a television? These are the questions of our times!
