Giant Microbes/Amazon

Assorted boxes of chocolate can be something of a letdown as there tends to only be a few worth eating. So skip the sweets this year and give them a box of plush microbes instead. Packaged inside a heart-shaped box, you’ll find an adorable plush kissing disease, a sperm cell, an egg cell, a penicillin, and a pink amoeba.

Scientific minds like to break things down and examine them from every angle—including kissing. In this book, author Sheril Kirshenbaum looks into the history and science of smooching, from when humans first started puckering up to why men and women kiss differently.

4. Heart Coasters; $20

Hearts are the universal symbol of Valentine’s Day, but this gift is for anyone who just can’t stand to look at the very anatomically incorrect pink and red ones that adorn most cards. These glass coasters all feature an illustration of a different part of the human heart, and when they're stacked together, they form the whole thing. And since the coasters are coated with a sealant, you can rest a sweaty drink right on top and the images won't come off.

Now that Prime Day is over, and with Black Friday and Cyber Monday still a few weeks away, online deals may seem harder to come by. And while it can be a hassle to scour the internet for promo codes, buy-one-get-one deals, and flash sales, Amazon actually has an extensive coupon page you might not know about that features deals to look through every day.

As pointed out by People, the coupon page breaks deals down by categories, like electronics, home & kitchen, and groceries (the coupons even work with SNAP benefits). Since most of the deals revolve around the essentials, it's easy to stock up on items like Cottonelle toilet paper, Tide Pods, Cascade dishwasher detergent, and a 50 pack of surgical masks whenever you're running low.

But the low prices don't just stop at necessities. If you’re looking for the best deal on headphones, all you have to do is go to the electronics coupon page and it will bring up a deal on these COWIN E7 PRO noise-canceling headphones, which are now $80, thanks to a $10 coupon you could have missed.

Alternatively, if you are looking for deals on specific brands, you can search for their coupons from the page. So if you've had your eye on the Homall S-Racer gaming chair, you’ll find there's currently a coupon that saves you 5 percent, thanks to a simple search.

To discover all the deals you have been missing out on, head over to the Amazon Coupons page.

This Four-Layer Face Mask Has a Two-Speed Fan Inside


This article contains affiliate links to products selected by our editors. Mental Floss may receive a commission for purchases made through these links. If you haven't received your voucher or have a question about your order, contact the Mental Floss shop here.

If you're looking for another face mask to bring with you while you're out and about, the Electric Respirator LED Fan Mask offers plenty of protection, thanks to a four-layer, KN95-certified filter and a two-speed fan motor for constant fresh air. And while it may sound like a massive contraption to wear, it’s actually a tiny geometric piece that's available in black or white.

The custom four layers of filters in the Electric Respirator LED Fan Mask are designed to keep the air you breathe safe and clean, which starts with a strong anti-bacterial net to filter large particles in the air. Anything that gets through there will be checked at the second filter—the activated carbon filter, where particles are sterilized and deodorized. It’ll even keep you safe from harmful substances like formaldehyde.

If stubborn particles like pollen, smoke, and dust still make their way through the first two layers, they’ll be faced with a HEPA filter at the third layer. A fourth and final layer works to inhibit bacterial growth through the release of negative oxygen ions. The two-speed fan motor doubles down on moisture prevention.

You can get the modern four-layer mask in black or white, and for a limited time, you can get them each in black or white two-packs for $87.

Prices subject to change.
