Hello, I would make a cocktail machine, so the Immersible Water Pump
interests me (robotshop.com/en/immersible- … -tube.html). But I have a question before buy it, can I use this pump to make cocktail (with alcohol) and drink it after ? There is no some chimicals (and dangerous) products in the tube ?
Thanks, and sorry for my bad english 
The pump is really meant to be used under water and when it comes to cocktails, it would need to be submerged in the liquid, and not work if that liquid ran out. You might instead consider:

robotshop.com/en/6v-micro-water-pump.html
These use standard ABS plastic, so not toxic. If you really want the pump to be submerged, we can check to see what materials are used in the tubing.
