Quick Answer

An egg timer web tool lets you measure exact times like 9 minutes for boiling eggs using only 4-minute and 7-minute hourglasses through strategic flips and staggering—no precise clock needed[3][4]. Start both timers, flip the 4-minute one when it ends, then flip the 7-minute one at the right moment to hit 9 minutes precisely[1][3]. Perfect for math puzzles, cooking demos, or low-tech timing challenges[5].

Why You Need This

The classic egg timer puzzle tackles measuring non-standard intervals, like 9 minutes with 7-minute and 4-minute timers, by combining runs and differences—essential for math education on the Euclidean algorithm and Diophantine equations[1][2][3]. For example, 80-second and 45-second timers solve 30 seconds via 3×80 - 6×45 = 30, while 7- and 5-minute timers hit 13 minutes sequentially[2][3]. Real egg boiling takes ~860 seconds (~14.3 minutes), making these tools ideal for students, puzzle fans, and chefs without digital timers[4]. Puzzles date back to at least 2006, teaching problem-solving sans calculators[1][5].

How It Works

Input your timer durations (e.g., 4 and 7 minutes) and target time; the tool simulates flips to find linear combinations like xA + yB = target, where GCD divides the goal[1][2]. Step-by-step: Start both; flip 4-min at end (now 4 min left on 7); when 7 ends, flip 4-min again; at next 4-min end, flip 7-min (1 min run + prior = 9 min total)[3][4]. Visualizations show sand flow for clarity[5].

Tips for Best Results

  • Ensure GCD of timers divides target for solutions (e.g., GCD(7,4)=1 works for any integer)[1][2].
  • Prioritize positive coefficients and minimal flips; test small cases like 7 & 4 for 9 min first[1][3].
  • Simulate sequences physically or via tools for validation—share as educational content[2][5].
  • Scale to variants like 13 minutes with 7- and 5-min timers for practice[3].
