Need an explanation for some observations observed

[Phoenix1300]

First off - Sorry I didn't use the template. I didn't see how I could fit my observations with the template. :(

I have 3 tubes of different lengths. They are both marked X and O on the ends. When I press on the X end or the O end and let it "spin", only the character pressed on is displayed. When viewed on top of a transparent glass, the character that we didn't press on appeared.

When the "spin" was viewed under a strobe light, I could see both the X and the O.

I tried the "spin" many times, and it seemed to me as if the it is both rolling & rotating using the end as its axis.

Can any explanation for this?

Please tell me if you need me to elaborate.

Thank you

My explanation for this phenomenon is that the tube is rolling and rotating simultaneously. When the end is pressed on, it causes the tube to rotate and roll in one direction, which makes the character on the end visible. When the other end is pressed on, the tube rotates and rolls in the opposite direction, making the character visible on the other end. When viewed under a strobe light, both characters are visible because the strobe light is capturing the tube in different positions as it is spinning and rolling.

Based on your observations, it appears that the tubes are exhibiting both rolling and rotating motion when "spun" on their ends. This is supported by the fact that both the X and O characters are displayed when viewed under a strobe light, indicating that the tubes are rotating and the characters are appearing due to the persistence of vision effect. Additionally, the appearance of the character that was not pressed on when viewed on top of a transparent glass suggests that the tubes are also rolling, with the unpressed character being revealed as it moves across the glass. This behavior could be due to the shape and dimensions of the tubes, as well as the force applied when pressing on one end. Further experimentation and analysis would be necessary to fully understand the mechanics behind these observations.
