From sunglasses for dogs to bottled rainwater, click or scroll through some of the most unusual products you can buy. All dollar values in US dollars.

During Boston's record snowy winter in 2015, husband and wife team Kyle and Jess Waring set up a business shipping fresh snow and 'snowmen in boxes' to people deprived of the white stuff. Launched as a joke, the business has since become a resounding success, turning over thousands of dollars.

Building on the success of their snow-selling business, the Warings also established a leaf-selling enterprise too, mailing out hand-collected, preserved New England leaves to buyers worldwide. To date, Ship Foliage has sold over 1,800 leaves.

Like Ship Snow, Yo, Vitality Air was started as a joke. The Canadian company sells bottled air from Lake Louise in the Rocky Mountains for $32 (£22) per canister. The canisters sell particularly well in China, and demands spikes when air quality worsens in polluted cities like Beijing and Shanghai. The air is also marketed to athletes to help them with recovery and even pregnant mothers who want a break from polluted air.

The perfect break-up revenge gift, Dirty Rotten Flowers charges from $30 (£21) to send a bouquet of decaying flowers to whoever you choose.

Taking the upcycling trend to the extreme, Fallen Furniture is a British company that turns airplane scrap into desirable pieces of furniture. Standout models include chairs made from Boeing 737 engines and emergency exit doors repurposed as coffee tables.

Potato Parcel is the brainchild of Alex Craig from North Texas, who launched the company half-jokingly. The firm, which can stamp the message of your choice on a spud for $14.99, is turning over thousands of dollars a month. The business also prints faces and pets on potatoes.

Artisans at this ethical fur company based in Massachusetts work with 'accidental fur' recovered from highways in the state to produce a range of apparel. Items on sale include pom pom hats, neck wraps and equestrian helmet covers. 

These sunglasses for pooches were invented in 1997 by Roni Di Lullo, who wanted a pair of shades for her squinting dog. The Californian native launched the sunnies soon after, and the company was raking in over $3 million (£2.4m) a year back in 2015.

Namsan's Dog Umbrella is attached to the leash so you can help keep your canine friend dry during wet walks. The umbrella-leash has a C-shaped handle which is extendable to make it easy for you to walk your dog while the umbrella covers it. Namsam also sells other pet accessories including dog diapers and pet stairs to help them into your bed.

Northern Irish travel company MyBaggage is selling bottled British rainwater to expats in countries such as Australia and Spain who are looking for a taste of home. The 500ml water bottles, which have a special nozzle to give the effect of rain, are on sale for £20 ($28).

 

Who doesn't love the feeling of fresh grass between their toes? KUSA flip flops have created sandals with synthetic grass soles so that you can feel the grass beneath your feet wherever you go. They sell for $19.95 (£14.10).

 

Yes, you read that right. Literally a rock in a box of hay, complete with breathing holes, this simple toy was invented by former advertising exec Gary Dahl in 1975, who marketed the rock as a pet that requires absolutely no caring for. Dahl came up with this unique idea when listening to his friends complain about having to look after their actual real-life pets. Dahl earned up to $15 million (£6m) during the mid-70s, despite the Pet Rocks only costing $3.95 (£1.60) each.
