Adm Note: I post a few pictures that can not be posted here almost every day to ourbottomsburn.bdsmlr.com. New logins to bdsmlr have been closed for months, and I have no idea if they will ever allow new registrations again. However, a few of the lastest posts will be displayed.
It was nice to be able to post any content to the ourbottomsburn website. But what turned out to be a $200 a month cost to me was a little much.

Written by a loyal reader:
Since I am not an expert at Physics, I went to the expert. The answer below is from Artificial Intelligence. I phrased the question to ensure no Kink filters were activated.
Question Posed:
Regarding the physics of a flat body such as a wooden plank striking a surface, does the plank strike the surface harder if there are air relief holes in the plank?
The Answer returned:
At the speed of a normal human arm swing (roughly 10–20 m/s for a fast strike), the presence of air relief holes in the plank would make a small but potentially noticeable difference in impact force, though not dramatic. Here’s why:
Factors Affecting Impact Force
Air Cushioning Effect (Minimal at Human Swing Speeds)
- Without holes: When the plank gets very close to the surface, air is momentarily trapped and compressed, which slightly reduces the impact force.
- With holes: The holes allow air to escape more easily, reducing this slight cushioning effect, leading to a marginally harder impact.
Aerodynamic Drag (Negligible at This Speed)
- At 10–20 m/s, air resistance is present but not a dominant force.
- If the plank were moving at very high speeds (like 100+ m/s), reducing drag via holes would matter more.
- At arm-speed velocities, drag reduction from holes would have an insignificant effect on the plank’s speed before impact.
Mass and Structural Integrity (More Important Than Air Resistance)
- Adding holes reduces the mass of the plank. If mass is reduced significantly, momentum (p=mv) decreases, which could actually reduce impact force.
- If the structure weakens due to too many holes, the plank could flex or deform, dissipating some impact energy.
Final Verdict
- Small Holes (Properly Spaced): Might allow slightly harder impact by reducing air cushioning.
- Large or Many Holes: Could weaken the plank and reduce impact force.
- At Human Speeds: The difference is minor, but in extreme cases (large surface area and very fast swings), the effect might be perceptible.
So, while air relief holes might slightly increase impact efficiency, their effect at human arm speeds is relatively small compared to the plank’s weight, stiffness, and how it's swung.

I made several paddles as gifts, like the one on the second from the right. I used Popular wood which is "light". I blindfolded my three "nieces" and paddled them several times with and without holes. It was, at best, a coin toss as to which paddle they thought I was using.
A human might detect a difference for a long wide frat-style paddle.
Based on the evidence presented, I claim holes in paddles make no discernible difference.
What's this? Science for Spanko's???... Agree with the general conclusion but have sampled a Spencer /holey paddle. My mileage found the difference notable. An additional variable could be the size of said holes, since that appears to be widely varied amongst paddle makers. In theory, those could contribute to perceived feel differential via velocity, air cushioning and mass factors; not to mention the tendency to leave those cute, or wicked, depending on one's thinking, little blisters 'behind'.
ReplyDeleteI'm not into holes, a flat thin paddle is fine especially when used with a wrist motion and not a full swing which can often land like a club. Lately, we have just used the belt which she absolutely has e wondering "what was I thinking" long before she stops, when I asked her to use it one time and it is her favorite now because it really gets me dancing.
ReplyDeleteIf you disagree with AI, you may be marked as nothing more than a greasy stain on the driveway.
ReplyDeleteSecond, some Spencer paddles are large enough to be affected by air resistance.
Third, You were not paddled with a Spencer with and without holes.
My tests on my nieces were only two licks with and two licks without holes. I varied which paddle was used first to allow for the effect that the third lick was going to sting more than the first.
Do me a solid and drive the bus friend Bogey, should you ever observe me arguing or attempting to reason with a machine (vending and slot machines excepted). Instead I'll go see if Sarah and John Conner need any help dispatching those pesky Terminators!
ReplyDeleteHonestly, I know little about applied physics when it comes to swinging a paddle. In my opinion the paddles with holes just give the look of being a more severe spanking instrument
ReplyDeleteI think it’s more a mind game. It’s like what’s really the difference between a spanking over panties or on the bare bottom? Little difference actually. But visually it may appear to be more severe on the bare bottom.
"I know little about applied physics when it comes to swinging a paddle." That's what we have AI for to tell you how to think. It's Elizabeth Warren behind the screen.
Delete"...what’s really the difference between a spanking over panties or on the bare bottom". There is a difference. Even sheer panties provide a little protection. Signed, a former panty wearer. Bacall always liked to start out in panties, but she wanted to end bare bottom. She knew there was a difference.
