Power to idle, back pressure until stall then full back and full left rudder to enter the spin. Recover when below the cloud.👹👹👹👹
I'm going to use the entire panel...attitude indicator, turn and bank, altimeter, visit, and Asi.
Stop any turn and center ball, note heading, then standard rate 180. Breathe
I always wondered about that vfr into imc scenario, how does that happen? Then one crappy day just west of Slave Lake Alberta I dang near did that. My wife is the worlds bravest airplane passenger.

Some good replies, but the best thng to do is what Columbo had to say:
Stop any turn and center ball, note heading, then standard rate 180.
Since you had been following a heading before you entered the clouds, you should know what the 180 degree heading is and so there fore, you should start a "standard rate" turn by placing the vertical needle on the turn and bank indicator, on one of the little "dog" houses, which would tell you that is the bank angle for a 3 degree per second turn, which is a standard rate.
As you start your turn, make note of the altimeter and if it shows any movement, correct at once!
as you turn, scan only the instruments which will keep you flying safely, the altimeter, turn and bank indicator, and if you have one, the attitude indicator, or artificial horizon. Of course, you would also want to scan the clock, as it will tell you when to roll out of the turn, 60 seconds, which will give you the 180 degree turn heading that you want. If you have one, the directional gyo will be helpful in returning to the 180 degree turn heading.
When I was a pilot designated examiner, I expected the private pilot applicant to be able to demonstrate this via the old "hood" and if he/she couldn't, they needed more training!
What I really looked for were the "tale, tale", signs that he/she was master of the aircraft.
