About this item
A new way to demonstrate thermal expansion in a metal.
- An alternative to the classic ball-and-ring thermal expansion apparatus
The bar and gauge allows learners to see how much the metal expands in both length and diameter. The bar, which fits closely into the gauge - either lengthwise or through the holes - will be noticeably longer once heated. Your hands are kept safe by a 8.25" handle with a wooden grip. Transform the traditional "magic trick" discrepant event into a real learning experience without losing any of the "WOW" factor.
