why, so you can fool someone into accepting a zero-confirmation transaction, only to send the funds back to yourself?
anyway, the easiest way is to use something like double-spend.py---see here: https://bitcoin.stackexchange.com/a/32347

Basic usage:
./double-spend.py <address> <amount>
Creates two transactions in succession. The first pays the specified amount to the specified address. The second double-spends that transaction with a transaction with higher fees, paying only the change address. In addition you can optionally specify that the first transaction additional OP-RETURN, multisig, and "blacklisted" address outputs. Some miners won't accept transactions with these output types; those miners will accept the second double-spend transaction, helping you achieve a succesful double-spend.

What do you mean by pay the change address? Can I have a live demo ? The tools isn’t working well according to the comments.
Thanks
