Story summary

In Japan, researchers developed a non-destructive testing method using bubble wrap to detect flaws in pipes.
Led by Professor Naoki Hosoya, the team shows bubble popping sounds can identify foreign objects with a 2% error margin.
The approach is safer and more cost-effective than traditional methods that require heavy equipment and electricity.
The system uses a microphone and wavelet-based analysis to track sound reflections.
