Following working models are courtesy - Arvind Gupta Toys

squeeze pumpSqueeze pump 1

Make a pump with just an old bottle and some cello tape.

 

squeeze pumpSqueeze pump 2

Try making this with a small variation. A coin does the trick.

 

Inertia pumpInertia Pump:

Modifications of this simple pump is still used in parts of Andhra Pradesh to lift water.

 

Inertial valve pumpsInertia and valve pump

An extension of the previous pump

 

Straw SpinnerStraw sprinkler

With an ordinary plastic straw, broom stick, cello tape and scissors
you could make a real centrifuge in a jiffy.

 

Straw SpinnerOne Minute Film

One minute film on how to make this

 

Coin PumpCoin pump

Make a water pump using a film can, bottle cap, coin, cycle spoke and other trinkets

 

Rotary PumpRotary Pump

This pumpis like the one used to draw water from a well

 

Jumbo PumpJumbo pump

 


Pipe and bottle cap pumpPipe and bottle cap pump

 

 

Rubber Bulb PumpRubber Bulb pump

Try a variation and use a syringe instead of a film can

 

Jumbo Syringe Pump Jumbo Syringe pump:

 

 

Air Water PumpAir Water Pump

This pump can be used to lift large quantities of water

 

Toothpaste tube pumpToothpaste tube pump

Finished with a toothpaste tube? Not just yet. Try out this pump instead of throwing the tube in the dustbin

 

Two straw pumpTwo straw pump

A couple of straws, some beads and ball bearings is all you will need to make this pump

 

Pen PumpPen 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

 

Pen PumpPen Pump 2

Use a straw instead of the pen body

 

Syringe pumpSyringe pump

You can make a simple force pump using two plastic syringes and other common things

 

Hand PumpHand pump

Understand the working of a hand pump

 

JCB TruckJCB Truck

Designed by V C Kandkur, understand the principle of hydraulic pressure and make this JCB truck

 

Submarines Submarines

This experiment shows you how a submarine works. Jazz up the bottle to make it look like a real submarine
