<p>[QUOTE=&quot;imrich, post: 8424619, member: 22331&quot;]You are correct with a partial answer inasmuch as the thermal coefficient of plastic expansion is greater than metal.</p><p><br /></p><p>The phenomena may/will be seen/experienced as elongation/expansion/buckling of plastic siding/rain-gutters on a hot day.</p><p><br /></p><p>A possible solution is to turn the capsule open side down in a transparent bowl with water being slowly heated.</p><p><br /></p><p>Water may be a pseudo-lubricant, and even heat distributor!</p><p><br /></p><p>The captive gas above the coin should/may expand helping push the coin out downwards, while the circumference of the plastic increases, possibly releasing the coin because of gravity/coin-weight. The coin may be viewed dropping, unless the diameter has been distorted to egg shape.</p><p><br /></p><p>A more probable solution is to slam the open end of the container downward on a hard surface, with a snapping action, where kinetic energy caused by the moving/stopping coin weight may simply release the coin if starting with a small vertical distance moved, to an increased distance and speed.</p><p><br /></p><p>Watch your fingers when using this approach!</p><p><br /></p><p>There are other non-destructive methods if neither of these work, but the 2nd suggestion is the simplest if the container is still round.</p><p><br /></p><p>JMHO[/QUOTE]</p><p><br /></p>
