I’m glad I subscribed to The Curiosity Show on YouTube. It features segments for 1990s Australian TV for young people, and is full of DIY science demonstrations, brain teasers, tricks, and optical illusions. In this clip, the hosts demonstrate a fun card trick you can make at home.
By the way, if making trick cards interests you, I wrote a book about it a few years ago, called Trick Decks.
