This is how to make a Mexican Jumping Bean out of tin/aluminum foil. The mexican jumping bean is a toy that bobbles in your hand aimlessly. Show them to your friends and maybe make a few bucks selling them too!

Step 1: Materials:

Materials:

Tin/aluminum Foil
Marble
cup/bowl
scissors

Optional:

Colored Foil
Coin (to flatten foil)
Ruler
Thick pen/marker

Step 2: Prepare the Foil

Cut out a rectangular piece of foil measuring about 7cm by 12cm. Roll the foil around your finger, a thick pen, a marker etc. depending on how big your marble is. Now you should have a cylinder-like piece of foil.

Step 3: Inserting Marble and Finishing Bean

Place marble inside of your foil. Make sure that there is enough room for your marble to move back and forth throughout the foil. Close up the sides of the foil with the marble in it. Make sure you do not dent the bean or else the marble will not be able to move throughout the foil. Test it by shaking the bean to make sure the marble can move freely. Remember the bean is fragile!

Step 4: Get Cup/bowl

Put your bean inside of your cup/bowl and shake it for about 20-30 seconds. The edges of the bean should become a little bit smoother. Test once again to make sure the marble is moving inside of the foil. Notice how smooth the edges are now.
