Title: "Scientists Reveal Simple Hack to Stabilize Wobbly Tables Without Coasters"

This title captures the core message (scientifically supported solution), avoids mentioning the coaster method, and stays within 15 words. It uses "hack" to imply simplicity and novelty, while "stabilize" clearly addresses the problem.

The Science Behind Fixing a Wobbly Table (And Saving Your Pint)

We’ve all been there: a wobbly pub table threatening to spill drinks. While many resort to stuffing coasters under a leg, scientists reveal a simpler, more effective solution—no coasters required.

The Rotation Method

In the early 2000s, physicist André Martin at CERN tackled this issue after endless frustration with uneven tables. His solution? Rotate the table. For a square table with four legs, even on uneven ground, there’s always a position where all legs touch the floor. Here’s how it works:

1. Identify the “floating” leg (e.g., leg D).
2. Rotate the table 90 degrees, keeping the other three legs (A, B, C) grounded.
3. Stop mid-rotation: At some point, leg D will touch the ground due to the surface’s unevenness.

While the table might not be perfectly flat, the wobble disappears. This relies on the intermediate value theorem: if a leg moves from above to below ground during rotation, it must touch the surface at some point.

Alternative: The Press-Down Method

For soft surfaces, press down on the edge between the floating leg (D) and a grounded one (A). This forces D into the ground, stabilizing the table—though it might tilt slightly.

Expert Insights

Physicist Keith Devlin (Stanford) explains, “Between the start and 90 degrees, the floating leg must touch the ground, eliminating the wobble.” However, this method works best for uneven floors, not uneven legs.

The Math Behind It

Hannah Fry (Cambridge) simplifies it: If three legs are grounded and the fourth moves from “above” to “below” the floor during rotation, there’s a midpoint where all four touch. No guarantees of a flat table, but no wobble!

Quick Guide to Fixing a Wobbly Table

1. Use a square table with four corner legs.
2. Rotate the table while keeping three legs grounded.
3. Stop when the fourth leg touches the floor.

Next time your table wobbles, remember: a quick spin might save your pint and impress your friends!
