Introduction: Ecological and Antiviral Travel Thermos for Drinks
An ecological and antiviral travel thermos for drinks, with materials that are available and very low cost.
A glass jar with a metal lid.
A copper tube 6 mm thick and long depending on the jar.
Plastic sheet with bubbles.
Wide plastic tape of one adhesive aspect.
Two neodymium magnets (from computer hard drive)
2-element epoxy adhesive.
Hot silicone rods An anticoagulant syringe cap.
Step 1: Bottom and Side Jar
Attach a magnet with epoxy glue to the outside of the bottom and th the side of the jar.
(Consult the instructions for use of the glue)
Step 2: Plastic Sheet With the Bubbles
Cut the plastic sheet with the bubbles to the necessary dimensions of the bottom of the jar and its perimeter.
Step 3: Glue the Plastic Sheet With the Bubbles
Glue the plastic sheet with the bubbles to the bottom of the jar and its perimeter with the hot silicone gun. (Care must be taken not to burn or burst the bubbles)
Step 4: Copper Pipe
With the copper cutter, cut the tube to the required size depending on the glass jar and how much you want it to be out of the jar.
Step 5: Copper and Lid
Drill the metal lid of the jar with a 6 mm drill.
Glue the copper tube from inside and outside with epoxy glue without touching the bottom of the jar and coming out of the lid to the desired height. (Consult the instructions for use of the glue)
Step 6: Stick the Wide Plastic Tape
Stick the wide plastic tape around the perimeter of the jar with the color you want.
Step 7: Mouthpiece
Remove the plastic cap of the syringe needle with the anticoagulant to be placed as a cap on the copper tube. (Mouthpiece)
Step 8: The Final Project
So. We have a glass jar that with a little care does not break and can be easily washed without leaving marks.
Glues to any metal surface that a magnet sticks to.
It does not have a plastic straw (pollution) but a copper tube that does not easily catch viruses.
It is so cheap and easy to make that if it breaks or is damaged by washing, make another one.
