Squeeze pump 1 |
Squeeze pump 2 |
Inertia Pump: |
|||
 |
Make a pump with just an old bottle and some cello tape. |
|
Try making this with a small variation. A coin does the trick. |
 |
Modifications of this simple pump is still used in parts of Andhra Pradesh to lift water. |
Inertia and valve pump |
Straw sprinkler |
One Minute Film |
|||
 |
An extension of the previous pump |
 |
With an ordinary plastic straw, broom stick, cello tape and scissors
|
|
One minute film on how to make this |
Coin pump |
Rotary Pump |
Jumbo pump |
|||
|
|
Make a water pump using a film can, bottle cap, coin, cycle spoke and other trinkets |
 |
This pumpis like the one used to draw water from a well |
 |
|
Pipe and bottle cap pump |
Rubber Bulb pump |
Jumbo Syringe pump: |
|||
 |
 |
Try a variation and use a syringe instead of a film can |
 |
||
Air Water Pump |
Toothpaste tube pump |
Two straw pump |
|||
 |
This pump can be used to lift large quantities of water |
 |
Finished with a toothpaste tube? Not just yet. Try out this pump instead of throwing the tube in the dustbin |
 |
A couple of straws, some beads and ball bearings is all you will need to make this pump |
Pen pump |
Pen Pump 2 |
Syringe pump |
|||
 |
Using an old pen body as cylinder, thread wrapped bicycle spoke as piston and a cycle ball bearing as a valve you can make a very workable pump |
|
Use a straw instead of the pen body |
 |
You can make a simple force pump using two plastic syringes and other common things |
Hand pump |
JCB Truck |
Submarines |
|||
 |
Understand the working of a hand pump |
 |
Designed by V C Kandkur, understand the principle of hydraulic pressure and make this JCB truck |
 |
This experiment shows you how a submarine works. Jazz up the bottle to make it look like a real submarine |
Water turbine |
Water turbine 2 |
||||
 |
Make this turbine first |
|
Try the hydroelectric power generator model detailed on this site |
