The Ultra Shaker

By Silas Howard

     First I got some bottles from the recycling bin.  I choose two small bottles and one big bottle.  Next my mom and I went to the store to buy some duct tape.  Then I got some rocks and pea stone from the pile of rocks in my subdivision.  I went back to the house and put the rocks in the bottles.  I put the big rocks in the big bottle and the pea stone in the smaller bottles.  I covered the bottles with duct tape, and then connected the smaller bottles to the bigger bottle with duct tape.

     The Ultra Shaker is covered with orange duct tape.  Two Gatorade bottles are attached to a two-liter Mt. Dew bottle.  The bottles have rocks and pea stone in them.

     The sound is made by rocks hitting the bottles when you shake it.  If you shake the Gatorade bottles when they are not attached to the two-liter Mt. Dew bottle they make a higher pitched noise because the rocks are smaller.  If you shake the two-liter Mt. Dew bottle when it is not attached to the Gatorade bottle it makes a lower pitched noise because the rocks are bigger in the Mt. Dew bottle.  Them being attached together makes a lower pitched noise because the high pitch gets a bit muffled.  To make the dynamic softer you have to shake it lightly and slowly, and to make it louder you have to shake it harder and faster.  The timbre is loud and rocky.
