Found a Long Metal Tube with a Plunger? Here’s What It Is and How to Use It
Discovered a metal tube with a plunger and tiny claws in your kitchen gadgets box? Learn what it is, how it works, and creative uses around the kitchen.
You’re rummaging through a box of old kitchen gadgets, and suddenly, you spot it:
A long metal tube with a plunger at the top.
When you push it, tiny claws spring out the bottom.
You stare at it, puzzled. What on earth could this do?
Relax — you haven’t found a gadget from a sci-fi lab. In fact, it’s a surprisingly practical kitchen tool that many people forget exists.
What This Gadget Actually Is
The tool you’re holding is commonly known as a corn cob peeler or kernel remover, sometimes called a plunger-style grabber tool.
Here’s how it works:
-
The long tube houses a set of small metal claws at the bottom.
-
Pressing the plunger causes the claws to extend.
-
You press it into a corn cob, or occasionally other round fruits/vegetables, and the claws grip and remove the kernels cleanly.
-
Releasing the plunger retracts the claws and deposits the contents.
Some variants are also marketed as apple corers or olive pit removers, using the same claw mechanism.
How to Use It
-
Prepare the corn: Husk and clean the cob.
-
Align the gadget: Place the claws over the top of the cob.
-
Push the plunger: The claws extend, grabbing kernels.
-
Pull straight down: The claws will strip kernels from the cob efficiently.
-
Release the plunger: The claws retract, and kernels fall out.
Tip: Work on a cutting board to catch stray kernels.
Why It’s Handy
-
Quick kernel removal – much faster than slicing with a knife.
-
Minimal mess – claws grab kernels cleanly.
-
Safe – keeps fingers away from knives.
-
Multipurpose – can also core apples, remove pits, or grab small vegetables.
Common Mistakes to Avoid
-
Using the wrong size claw – some cob removers only fit standard-size ears of corn.
-
Twisting instead of pressing straight – can damage the cob or bend the claws.
-
Skipping the husk removal – reduces efficiency and may damage the tool.
-
Not cleaning immediately – small claws trap food particles, which can rust if left.
Creative Kitchen Uses
While primarily for corn or apples, you can also try:
-
Removing pits from olives or cherries
-
Core small round vegetables like tomatoes or bell peppers
-
Grab small candies or nuts in recipes that require precise placement
-
Use for craft projects, like piercing foam for fruit displays or food decoration
Safety Tips
-
Keep fingers away from the claws when plunging.
-
Wash thoroughly after each use.
-
Avoid using on very hard or frozen food — the claws may bend.
