These Smart Water Bottles Run on Solar Power and Remind You When It's Time to Drink Up

The suggestion that people need to drink eight glasses of water per day is a long-held myth. While it’s important to stay hydrated, the amount of water you should consume on a daily basis depends on many different factors, including your age, sex, weight, activity level, and even your location.

A 24-ounce, double-wall insulated smart bottle called the Hydrade can help you figure out exactly how much water your body needs, then send reminders to your phone or other electronic device when it’s time to drink up. It pairs with your phone, health apps, or wearables like the Fitbit or Apple Watch.

Unlike other smart water bottles, though, this one is completely cord- and battery-free. It has a built-in solar panel that lets you charge it naturally when you step outside for a run or hike, and a single charge can power your bottle for up to 20 days. However, it also charges when exposed to any type of illumination—even indoor lighting.

In addition to knowing how much water your body needs, its sensors can also tell whether you’re drinking the water or pouring some out for your dog. The maker, Bazaarian LLC, says the Hydrade Bottle keeps beverages cold for 22 hours, and hot for up to 13 hours.

The bottle is made of dishwasher-safe, BPA-free stainless steel, so it’s eco-friendly and recyclable. There’s a charitable side to the business, too. Depending on your personal level of water intake, Bazaarian will donate a set amount of money to a charity that supports clean water initiatives in developing countries. You can track both your charitable donations and your hydration logs via the app.

Get the Hydrade Bottle on Kickstarter now for $35—a 53 percent discount off of the retail price.

Portable fireworks light projector.

If you want a low-hazard Fourth of July that still delivers thrills, consider getting a light show projector.

And it works indoors, so you can count on your Independence Day party ending with a light show no matter the weather forecast. (There's also a Disney version available for just $20.)

5. American Trivia Cards; $15

Even players who paid attention in American history class might find this game challenging. Each box comes with 150 cards of United States trivia. Some questions—like what was the first state to grant women the right to vote—highlight important moments in our nation’s history. Others—like how many columns the Lincoln Memorial features—are a little more random.

6. U.S. Navy Blanket; $200

The U.S. military has been going to Faribault Woolen Mill Co. for its blankets for over 100 years. This one is crafted from 100 percent wool and weighs 3.5 pounds. The design is inspired by the blankets supplied on Navy ships—and if it’s tough enough for the Navy, you can bet it will withstand a Fourth of July picnic. We like the gray version, but it comes in several different styles and colors.

7. American Flag Cornhole; $90

Two American flag cornhole boards with bean bags.

8. U.S. Map Cutting Board; $20

Wooden cutting board in the shape of the U.S. map.
Totally Bamboo, Amazon

This 100 percent bamboo board eschews the traditional rectangle shape in favor of the outline of the American mainland. You can either keep it in the kitchen and use it as a cutting board or bring it out to the party as a serving platter for fruits, cheeses, and other hors d'oeuvres.

Find it: Amazon

9. Boston Tea Party Tea Sampler; $15

Six piles of loose-leaf tea.
Solstice Tea Traders, Amazon

A sip of one of the teas in this sampler will put you in touch with your inner revolutionary. Each of the six loose-leaf varieties—bohea black tea, oolong, congou black tea, souchong, singlo, and hyson—was among those tossed over the sides of British ships during the Boston Party. Whether you drink the tea or chuck it into the nearest harbor is up to you. (If you're looking for something to put on display, UncommonGoods also sells a slightly pricier, more elegant option with five teas.)

Find it: Amazon

10. State Map Prints; $27 and Up

Turn Your Phone Into an Instant Camera With KODAK's New Handheld Printer

Instant cameras are all the rage, but when you're already carrying a high-end camera everywhere you go in the form of your smartphone, the idea of carrying around an extra gadget might seem like more work than it's worth. You don't have to choose between the convenience of your phone's camera and the fun of having a tangible memento. KODAK's new SMILE digital printer combines all the fun of using filters and image editing on your phone with the delight of having a printed copy of your photo.

The handheld Bluetooth printer—which is roughly the same size as KODAK's SMILE instant digital camera—lets you edit photos on your phone, then print your image instantly on 2-inch-by-3-inch sticker paper. Using the KODAK SMILE app, you can add Instagram-esque filters; rotate images and change contrast, brightness, and other characteristics; and add stickers, text, doodles, and borders.

Most uniquely, you can add augmented reality elements to your photos, so that when you (or someone else with the KODAK SMILE app) point the app at the physical print, the image is replaced by a short video clip. The effect is something like the moving photographs in Harry Potter—you can surprise your friends by asking them to view a photo through the app's AR function, then watch their delight as the still image begins to move.

KODAK sent Mental Floss both the SMILE instant camera and the SMILE printer to test, and while there's a lot of fun in snapping photos on an instant camera and accepting whatever weird flaws that photo might have (though you can do some light editing on the SMILE camera before printing), in our opinion, the breadth of image-editing features and convenience of being able to print photos you've already taken on your smartphone makes the digital printer the better option if you're trying to choose between the two.

This is especially true if you're going on vacation or trying to capture a night out on camera; it's just easier to whip out your phone rather than break out another camera, and it's easier to edit photos on your phone than to manipulate photos on the SMILE instant camera's small screen.

The SMILE printer is available on Amazon and Walmart for $100 and comes in five different colors: white, black, blue, green, and red. The SMILE instant-print digital camera is also $100 on Amazon and Walmart and is available in the same colors.

While the camera and the printer both come with a starter pack of sticker-backed ZINK photo paper, you can get 50 refill sheets for $24 when you run out.
