Great little gadget, with plenty of the reagents you need to make lots of little balls of things.Took some practice to get it to work right, but I was really satisfied with how my food turned out.We made spherical guacamole for a guacamole contest, and it was a hit!It's hard to clean, and if you don't use it exactly right it's really frustrating.Of note, the plastic "tray" part it comes with is for more than just protecting the little pipettes.Fill the tray itself with a fairly generous amount of the liquid to be spherified, and set the pipettes down into the tray until it's flush.Pull the syringe up until the pipettes draw liquid very close to the top of the pipes.Make sure every single pipette has a fairly large amount of liquid in it, because otherwise when you go to extrude the spheres, you'll have no air pressure when you squeeze the syringe.To clean it, do it the way a bartender cleans glasses:First, shake it vigorously in a sink full of soapy water, then shake it again in a sink full of just water.Repeat a few times until it's clean, carefully let the water drip out the bottom to dry. It takes a while.
