Growing up with brothers meant holidays and birthdays were spent not only wrapping gifts from me, but from them as well. And while I’ll probably never be on par with Macy’s gift-wrapping professionals, it turns out I could’ve been getting a little help from geometry all along.
Mathematician Katie Steckles does all kinds of cool things with math, so it’s only appropriate she uses equations and measurements to wrap her presents. In this video, she demonstrates several techniques for making rectangular boxes, packages with square cross-sections, Toblerones, and cylinders look their best when covered with festive paper. Finally, you can gift someone a can of Pringles using the perfect amount of wrapping. She also has a trick for wrapping up squishy gifts, like marshmallows. What? You don’t give your friends Pringles and marshmallows? What kind of friend are you?
One of Steckles’s coolest techniques is for relatively flat squares. You take a square piece of wrapping, place the box at an angle, and fold the corners so they meet in the middle. Mathematician Dr. Sara Santos showed Britain’s The One Show her formula for cutting the perfect square back in 2005. It involves measuring the diagonal and height of the box, but Santos says she wanted to use the least amount of paper and tape and have the paper’s pattern line up perfectly. Measure your present’s diagonal, then add it to one and a half times the box’s height to find the length of the paper’s sides. Put the gift in the middle of the paper and fold in the corners and tuck in the extra bits. It still takes some dexterity, but the result is an impressive-looking package your friend will admire for roughly 2.5 seconds before tearing it open.
Sadly, she doesn’t demonstrate how to wrap a bottle of wine without it looking like a total mess, so you’ll just have to keep investing in those bottle gift bags.
Outdoor security cameras are not always practical if you live in an apartment or rental. Drilling into an exterior wall may be off-limits, while pointing a regular indoor camera through a window can create another problem once reflections start showing up after dark.
Baseus is trying to solve both issues with the new PrimeSentinel W1, a $69.99 security camera designed specifically to monitor the outdoors through glass. It mounts directly to a window without drilling and uses a 4K Starlight sensor with an F1.0 aperture for full-color monitoring during the day and at night.

Technology evolves every day, transforming how we live and work. Our devices are becoming more than tools we use. They are increasingly capable companions that help streamline day-to-day routines and spark creative ideas. If you have been waiting for the right moment to upgrade your tech setup, the Discover Samsung Shopping Event offers an opportunity to explore what connected, AI-powered living can look like.
With AI progressing so fast, it's only a matter of time before we start getting AI companions like the ones we used to see in movies like R2-D2, Wall-E, or Baymax. Now, Singapore-based OKA Technology has unveiled Mori, a cute little AI companion that looks less like a conventional home robot and more like someone turned the Pokémon Foongus into a table lamp.
Mori isn't meant to clean your house or control your smart home, but to serve as what OKA calls a "Nature Companion." It uses subtle movements, warm lighting, nature-inspired sounds, and small reactions to make its presence around the house feel calming rather than distracting. Mori can sit quietly while you read, sway along to music, welcome you when you enter a room, or encourage you to slow down for a moment without requiring a screen or a conversation.
