This can also count as your best stupid human trick ;)
I can do this. So yeah.
Not really a party trick but my stupid human trick is wiggling my nose like from the show Bewitched, I can also move my ears... I honestly probably do more weird stuff, but just dont realize it
I can twist my hand more than 360 degrees. I could even further but I've stopped doing it.
I can move my ears, one ear at a time.
I can stick a finger down my adam's apple through the skin.
Don't really have anything exciting. I guess I cant fit my fist in my mouth, does that count?
Blowing out a candle and then really quickly relighting the smoke which then relights the wick. Its pretty cool if you've never seen anyone do it before. Also turning a bag of chips into a bowl is pretty cool and convenient.
