Baseball Bat from Rough Sawn Lumber
Adults DesignIn this video I make a baseball bat from scratch, using maple and walnut. Most baseball bats are made with a solid piece of wood such as ash, hickory or maple, however I thought it would look really cool to add some walnut. So, I first got three boards, two maple and one walnut, that were at least 40 inches long.
How Does A Sailboat Actually Work?
Adults DesignHow does a sailboat work? The standard idea is that the wind pushes the sails from behind, causing the boat to move forward. Although this technique is used at times, it is not the most efficient way to sail a boat (and it means the boat can never go faster than the wind). Lift is the key mechanism driving a boat forwards. As air flows over the sails, it moves faster over the outer side, creating lower pressure than on the inner side. This produces a force which is mostly to the side and a bit forwards.
