Designing a fast-confirmation bitcoin vending machine.
You want to walk up to the machine. Send it a bitcoin. Walk away eating your nice sugary snack. (Profit!)
How can I create a bitcoin transaction puzzle? Do I have to use a special address or can I use a regular p2pkh and its utxos?

When you send Bitcoin from your wallet to some other address it needs some time for transaction confirmation in the blockchain.
