This I got from a website by Arvind Gupta. I am just making it pocketable.
I have been playing with these things since my childhood. Students can make and understand chemistry from these models.
It just cost me Rs 50 =1$ to make few of them
So let's get started.
Step 1: Things Required
Not much is required to make this project
Cycle Valve tube
Large sewing needle (i just used a sharp tool here)
A tin can (I am using nivea can as I don't have access to altoid can where i come from)
Step 2: Prepare the Parts
Cut the valve tube in 1 inch pieces. Cut a little more than you think required.
Cut of the lighting tip of the match sticks.
These things will be the base of the project. So make as many as you can
Step 3: Prepare the Complex Parts
Pierce a hole in one of the valve tube pieces. Pass another valve tube through the hole to get a connector of 4
Pass another valve tube to get a connector of 6.
Step 4: Packing Everything
Put everything together so that nothing is lying around.
Step 5: Using It
This is a basic model that can be made. In this model I used just the 2 point connector. But you can use 4 point connecor or 6 point connector. Just leave 1 connection loose without the match stick.
Play around and have fun!
