You Can Not Break Me (Wired NextFest)
The Self-Healing Polymer created at the University of Illinois at Urbana Champaign has these tiny metal catalysts and microcapsules of dicyclopentadiene embedded in the plastic. When the plastic is scratched or broken, the microcapsules burst open and the healing agent reacts with the metal catalyst to bond the broken pieces. After 24 hours of curing, the material is back up to 90 to 100% of its original properties. In the future it might be possible to have them in ceramics and glass!
