A fidget that interests people of all ages with anxiety needs to be fun and easy to use, all without making adults feel childish. WTYCD's retro fidget toy does just that. The small game controller fidget is discrete and has eight different functions to play with and touch -- including four colored buttons, a joystick, a textured roller, a gear scroll, a switch, a dial, a keyhole and a pick. This fidget could be used at home, work, school or during travel, but be aware that two of the colored buttons do make a little noise (similar to a pen clicking). 

Use the keyhole to add a wristband or add to a keyring. 

Best features:

• Pocket-size and lightweight; fits in an adult's and a child's hand 
  
• Comes in eight different colors and designs, as well as a two-pack option for $10

In addition, the cube is made of soft textured rubber so each side is smooth and sleek. It is easy to rotate from one textured side to another and designed to keep your hands busy during long meetings, classes or anxious periods. It comes in six different colors. 

Be aware that the switch, buttons and gears make a small clicking sound.

Pop It balls combine two popular fidgets -- a pop it and a stress ball. This set of four balls is covered in plenty of raised bumps that can be pushed and squeezed. Made of non-toxic silicone, the rainbow colored balls are small enough to fit in the palm of your hand and are very lightweight. As a sensory toy, the fidgets offer texture, noise and stress relief to anxious hands. They're also easy to clean.   

If you decide to use these in a classroom, be aware that they do make noise.  

Best features:

• Makes popping sounds

Fidgets for children need to be entertaining enough to occupy their busy hands. These brightly colored, textured and plastic pop tubes are guaranteed to grab their attention. Each set comes with four pop tubes for one low price. Similar to Lego and other building blocks, you can even connect a few pop tubes together to make larger tubes. The rigid tubes can be pulled and bent to make shapes, letters or words. Every time a tube is pulled or pushed together, it makes a sound, similar to a bendy straw. Let your young kids play with these fidgets on their own or join in on the fun. 

However, be aware that the tubes can dented during rough play. If you use these in the classroom, be aware that they make noise. 

Best features:

• Fun texture and sounds 
  
• Can connect the tubes together for more play
  

These non-toxic, non-latex and hypoallergenic stress balls are great for students in the classroom. Each ball comes filled with jelly water beads, making them fun to squish and squeeze. One set comes with three water bead stress balls, and there are a few colors and sizes available. The best thing about these fidget balls is that they make virtually no noise, and therefore won't disrupt class. At home, students can also toss, bounce and play catch with these fidgets. 

Note that these fidgets might not be as durable as their more expensive counterparts.

Best features:

• Quiet, discreet stress ball
  
• Customer service will offer a refund or replacement within 90 days

When the body is under stress and anxiety, it often responds in a physical way known as fidgeting. This fidgeting is due to discomfort and can look like a tapping foot or having trouble sitting still. Fidget toys are a way to soothe this anxiety and keep the mind focused and calm at the task ahead. They can direct the anxious energy somewhere else, so your mind is clear enough to continue through a work meeting or an important lecture. 

The research on the effectiveness of fidget toys is still new, and has had mixed results. Some children and adults seem to benefit from fidgets, while others find them distracting. Many of the studies on fidget toys are about other uses, like improving attention and focus, rather than anxiety specifically. More studies need to be done. However, based on many first-hand accounts of those who use fidgets, they often can help calm the mind.   

Fidget toys are accessible and already fairly affordable. You can find cheap fidget toys on Amazon or in department stores like Walmart or Target. Your local grocery store might even carry a few fidgets.

However, Amazon usually has the best prices for fidget toys. They even offer variety packs of 50 small fidgets or less for about $20. Here's one variety pack for $17. 

The most stress-relieving fidget for you is a personal choice. While research on the effectiveness of fidget toys on anxiety is slim, there are many groups of people who swear by them. There are so many different kinds to choose and try -- from stress balls to Pop Its, fidget rings and cubes to fidget spinners. If one doesn't work for you, try another. 

If you aren't satisfied with the prices of cheap fidget toys online, you can always make your own at home. They are fairly simple and many require only a few materials. You can make a bead fidget toy with jumbo paper clips and any colorful beads (although, perler beads might work best). The possibilities are endless, and making these fidgets are a great arts and crafts project for young children.
