<human>: Can I use a syringe to inject liquid into a syringe?
<bot>: Yes, you can use a syringe to inject liquid into another syringe. You will need to make sure the needle is inserted far enough so that it touches the inside of the barrel and then pull back on the plunger until all the air is removed from the syringe. Then slowly push the plunger forward to draw in the liquid before finally injecting it into the second syringe.
