A man in Virginia invented a device that allows birthday candles to be blown out without spit flying all over.
The dad said he came up with the idea for the Blowzee birthday cake candle extinguisher while at a child's birthday party before the pandemic after he saw the spit flying in the air. The Blowzee allows children to still use their own lungs to blow-- but the air that travels over the cake doesn't come from their lungs.
There's a little electric sensor in there, so when you blow into it, you're activating the sensor, and it switches on the fan, and that creates enough clean air flow to blow out the candle.
