Another Star Trek Hypospray, this is The Original Series version. To assemble, Take the top plunger part and insert all the way through the main body. Then glue on the ring at the bottom of the plunger stem. Wait to dry and make sure that it does not move and that it is secure. You can then take the extruder/emitter part and glue that in place making sure that it does not stick to the plunger part. Then paint it a metallic silver colour and find vials of "medicine" to place in the end Make sure you don't get cortrasine poisoning! Please upload any makes! I would love to see what you do with them!
