Sand won't save you this time...
Yay! They're advertising a sports drink with extra 'zing': Chlorine Trifluoride -
Energy drink? No shit, Sherlock: I'd find the energy to run like f*** if I had to outrun an ClF3 spill.
It is, for your reference, hypergolic without detectable ignition delay in contact with all organic material. Athletes and terrified sand-surfers included. It will indeed, as the picture shows you, sent a sand dune merrily alight - the link above includes a 'hazards' section with a brief description of an incident in which a ton of it breached containment.
If you are aware of anything else that'll set alight a bucket of sand, let me know.*
[EDIT]
Originally posted with Oxygen Difluoride as the subject: I was mistaken - after polite comments from readers, and rereading the source Sand won't save you this time, it is indeed ClF3.
