Measure the length of your wooden load up in centimeters to partition it fifty-fifty, and imprint the load up at its midpoint. Lay the board on its midpoint over the 2" width chamber, and safely tape the chamber to the board utilizing the pressing tape. This makes a straightforward switch wherein the two arms of the switch are equivalent long.
Imprint the board at 7.5 cm from each end. Draw a circle, an "X", or spot a bit of tape at these focuses to fill in as targets.
Measure 200 mL of faucet water with a graduated chamber and move it to an unfilled 1 L soft drink bottle, utilizing a channel if necessary. Guarantee that the cap is in a bad way back on the container safely.
Spot a beanbag with the goal that it is fixated toward one side of the board at the objective.
Work on dropping the soft drink bottle on the objective at the opposite finish of the board, until you build up a technique in which the beanbag pops straight up and can be handily estimated by your lab accomplice, utilizing the meter sticks for reference. The meter sticks should be set start to finish and upeight close to the furthest limit of the switch, potentially taped against a divider. This will give a tallness reference scale to gauge the stature the beanbag is tossed.
