Mike of the YouTube channel Useless Duck Company was fed up with birthday cakes for two reasons: 1) Blowing out candles splatters germs all over the cake, which is gross and unsanitary; 2) If it's your birthday, why should you have to work by cutting your own cake?
So Mike came up with a new invention that "fixes birthday cakes" – a birthday cake candle made with model rocket engines that blows itself out and cuts the cake so you don't have to. Brilliant!
Here's the longer version of the video that shows how he made his rocket-powered birthday cake: https://youtu.be/9CiKvuTPHvI
