To drill a hole in a table tennis ball, you will need a sharp knife or a drill with a small bit. First, mark the spot where you want to drill the hole on the ball. Then, carefully use the knife to make a small incision or use the drill to slowly create a hole in the marked spot. Be sure to hold the ball securely to prevent it from rolling or moving around. Once the hole is made, you can use it for various crafts or to attach the ball to a string for training purposes. **

A dash is a punctuation mark that is used to separate or emphasize information within a sentence. It is longer than a hyphen and can be used in place of commas, parentheses, or colons to create a pause or break in the sentence. Dashes can add emphasis, provide additional information, or set off a phrase for clarity or emphasis. **

When using apposition, both commas and dashes can be used to set off the appositive phrase. Commas are more commonly used and create a lighter separation between the appositive and the rest of the sentence. Dashes, on the other hand, create a stronger break and can be used for emphasis or to draw attention to the appositive. Ultimately, the choice between comma and dash depends on the writer's preference and the desired tone of the sentence. **
