Food keeps longer in a vacuum, which is why there are so many hamburgers stuck in low Earth orbit. Today's Groupon vacuum seals meals without a space launch: for $29, you get a Frisper vacuum-sealer starter kit from Oliso (a $69.99 value). Shipping is not included in today's Groupon, but UPS ground shipping starts at $6.
Featured in O, The Oprah Magazine and House Beautiful, the Frisper empties air from food-storage sacks, imbuing comestibles with a shelf life of up to five times longer. Set one of the starter kit's quart- or gallon-size Vac-Snap bags between the Frisper's lips, and its single tooth will bite through the plastic at one of 10–12 pre-punched circle guides. As the Frisper sucks out the bag's air stuffing, it will also heat seal the hole so oxygen molecules can't sneak back in when you're not looking. A side light blinks green when the 30-second process is complete.
Once the vacuum-sealed fish fillet or alien-autopsy sample has been tucked in the refrigerator, test out the Frisper starter kit's other accessories. Stash dry goods inside a medium or large pantry bag with a plastic zip disk, whose magnet can stick conveniently to refrigerator doors or robot butlers. Both types of BPA-free bags can be reused, which can reduce household waste. Although the starter kit doesn't include Oliso's Freshkeeper jar and bottle toppers, it does include the Flexi Tube that can connect these to the Frisper. Designed by a San Francisco–based team of inventors, engineers, and research warlocks, the Frisper's sleek design embraces form as well as function. Customers choose between two color options: red or slate.
