Toothpaste: Emergency Thermal Paste?

I needed to test my colleague (Zhang Yifeng) 30W LED chip, he gave me a set of LiPo battery, an LED chip, and a heatsink - without the thermal paste.

With no proper paste in hand, I give toothpaste a try:

Pretty sure the double action was meant for teeth cleaning. :D

Just bear in mind that this is meant for temporary solution. Most toothpaste are a weak basic and it could potentially slowly etch aluminum surface.
