Back to the Roots Water Garden

Keeping a fish and gardening are both relaxing pastimes. Strange though, it might initially seem each of these ends can help serve the other.
We are referring to this peculiar 3-gallon fish tank.

In this tank, your fish can produce waste which plants protruding from the top of the tank can consume; the nutrients in that waste can benefit them. Then, filtered water can return to the fish's habitat to keep the water there clean and safe.

If you have a lot of keys, then keeping them all in one place can obviously assist you in preventing the annoyance of losing any. You can follow this piece of advice in an especially quirky manner by using this magnetic key holder, which can be firmly attached to a metal surface like a fridge door.

Electric Blower

While looking after indoor spaces can be straightforward provided that you keep a close watch on them, preserving the tidiness of residential areas that are exposed to the elements - think driveways, patios and garages, to cite a few examples of such areas - could often seem beyond you.

Buy It Here: Sun Joe SBJ601E 10 Amp 215 Max MPH All-Purpose 2-Speed Electric Blower, Green

How on earth did all of those leaves get there? No matter; just turn on this blower and watch the gusts send those leaves away. You can pick up this machine in green, red, blue or purple.

The Gift of Nothing

This article is all about things that you need, but sometimes, you need... nothing. Yes, nothing. Nada. Zilch. For those occasions, you could buy this little bit of nothingness.

Buy It Here Nothing a gift of Nothing

It comes in a bit of card and a transparent orb - but, once you open them, there's... nothing. Not a single thing. Savor the wonderful moment as you enjoy the complete and utter absence of any chocolates or flowers. It's quite possibly the most beautiful gift you could buy for yourself.

Benchmark Bouquets Big Blooms with Vase

Even if you often like to "say it with flowers", the idea of buying them from Amazon specifically might never have occurred to you. However, when it is one of these bouquets that you order through the site, you could be pleasantly surprised by how fresh they are when they arrive.

The flowers will be buds when they ship - which, we should add, will be overnight. There is no option for a Saturday, Sunday or Monday delivery. The blooms will take just days to open.

Flavored Crickets

We believe it is inevitable that at some point crickets will be the staple diet for the human race. Why not start practicing now? These crickets are edible and absolutely real. No chocolate or nuts in the shape of crickets here.

However, they do come in three different flavors: sour cream & Onion, bacon N' cheese, and salt & vinegar. Do wild crickets come in those flavors, too? Maybe we should taste a few to find out...

While nibbling on random crickets, you could look through Amazon to see what other amazing products they offer. You might even find something that would taste great with a cricket kebab...
