First, Would You Smear a Ballpoint Pen under Your Armpits?

Of course you would, like millions of people do every day.

When Helen Barnett Diserens came up with the deodorant roll-on at Bristol Myers in the 1940s, she took inspiration from a recent invention: ballpoint pens. Who would not smear them under their armpits after all, if they smell nice?

Time needed: 3 minutes.

To quickly change the size of an image (so it will perfectly fit an email signature, for instance) in Paint 3D on Windows:

  1. Open the image you want to resize in Paint 3D.

    Tip: Click on the image with the right mouse button and select Edit with Paint 3D from the context menu that has appeared.
    Alternative: You can also highlight the image and select Open | Paint 3D from the Open section of the Home ribbon in Windows Explorer.

  2. Click Canvas (Paint 3D Canvas Icon).

    Click "Canvas"

  3. In the sidebar, check Resize image with canvas.

    Note: If you do not see the sidebar click the Canvas icon in the sidebar or press M. The entry in the sidebar may also read When resizing the canvas, adjust my image as well.
    Tip: You can also have the sidebar permanently expanded in Paint 3D.
    Also: Want to focus your image before resizing it? You can cut rectangles and squares or even crop a circle in Paint 3D.

  4. Check Lock aspect ratio as well (under Resize canvas).

  5. Finally, select Pixels under Resize canvas.

  6. Enter the maximum height or width under Height and Width respectively.

    Note: The numbers are connected so the ratio of width to height stays the same. If you change one, the other automatically adapts to it.
    Tip: Watch both numbers, and if one exceeds your desired maximum size, switch to it and enter the maximum there.
    Example: You are resizing an image for your signature. The image should not to exceed 100 pixels in width, and you don’t want it be higher than 95 pixels. The image’s original size is 2448 × 3264 pixels.
    After you enter “100” as the new width, the height changes to “133”. That is too large, so you enter “95” under Height instead, and resize the image to 71 × 95 pixels.
    Enter the maximum height and width to resize an image in Paint 3D

  7. Click the menu button.

  8. Select Save.
