Candy name: H1-oween Shots
How cool would it be to give out treats this year in syringes for Halloween? You would even need to carry out the elaborate and somewhat tricky 'spherification' process described in this post, just have the kids line up one by one and direct the concoction straight into their greedy mouths from the nozzle of your needle-less syringe. Maybe better for a party than for trick-or-treaters at the door owing to logistics and trust factors, but we obviously have the technology.
Thanks to Holy Kaw for pointing me to this blog.
