Having the consistency of modelling clay when first taken out of the pack, Sugru can be easily moulded and fixed in place by hand, but will cure at room temperature over 24 hours to form a tough, flexible, heat resistant and waterproof rubber.
Wise words from Simon Pegg. Never be afraid to be yourself! Even if your interests are what someone else might consider "nerdy," if you are confident in your interests and in yourself, that will be admired. Never think it won't.
