Beginning :

It's nice that children use their imagination and creativity in making things beautiful craft.

Now,we will learn how to make Dozer in an easy way.

First Bring this objects or similar:

• Toilet Paper Tubes (Number 2).

• Coloring Tapes.
• Straws.
• Scissors(be careful).

1- Now make bulldozer blade:  

Simply cut one of your Toilet Paper tubes in half the long way,

Looks like a my bulldozer blade ! You can even cut the edges at an angle a little bit to make it even more cool.

2- Make arms:

Stand your blade up on to a piece of cardboard and trace out its circular edge,Then draw out your arm design(about three to four inches long), After drawing arms start cutting them and make a hole for the straw passes through them.

3- Make the axle holes:
make four holes onto your other  Toilet Paper tube, 

(Make it at the same level, So that each hole parallels the other) ,These holes need to be slightly bigger than your straws.

5- Make wheels:
draw four circles on an old box or piece of cardboard (about three inches in diameter) .
Then cut out all four wheels ( Be careful ) and Find the center of each wheel and make a small hole for straw axle to slide through (Don't make the holes too big,the wheels might wobble).
