I had a super time at Lee's party and was well appreciated by his guests, even though my voice was breaking up.

Effects that got the best reactions I think were:

Permanently inverting a chosen card,

Two chosen cards appearing in a glass and also on the card box,

Stealing someones's phone number and transferring it to my phone,

Hacking into the house wifi to reveal a chosen card,

Lie detector test with a coloured cube,

Signed card to wallet to locked box,

Sherlock Holmes book test,

Mind reading a card openly selected from a face up deck.
