Though often considered as a type of squirrel feeders, spinners are not exactly meant to feed the squirrels... well at least not to feed them easy way.
Primarily, squirrel spinners are designed to grab squirrels' attention, waste their time and keep them away from your bird feeder. Thanks to squirrels' curiosity, gluttony and stubbornness, good squirrel spinner is going to twirl around and eventually exhaust even the most persistent squirrels at the expense of several corn kernels. In the meantime, your bird feeder is safe from squirrel intruders, and that's the reason why so many people choose this way to bribe the squirrels while keeping them busy.
But there's more to it: people love squirrel twirlers because it's fun to watch squirrels knocking their socks off while trying to get that darn corn from cob! Just check this hilarious video of squirrel vs. homemade twirler and see it for yourself:
Besides from being both practical and fun to watch, squirrel spinners may also be very decorative. And of course, good thing is they come at very affordable prices.
Here are some spinners with decent feedback from people who bought them at Amazon.com:
