Darts? Fun. Beer pong? Funner. But you know what's not-so-fun? Having to stick tape to your beautiful floors to mark throw lines during your party. Go high-tech instead and try using lasers to mark your throw lines. One Instructables user tried a high-tech hack, but we have a way to make this a whole lot simpler—and it's not going to cost us a cent!
If you're planning a party to show off your new space, the last thing you want to do is mark up the floors with throw lines for your party games. Instead, take a cue from Instructables user stevemoseley.
He attached a small laser module, fitted with a line-shaped lens, to the inside of his dart board cabinet. It stays mostly out of sight, but when the lights are turned on inside the cabinet, it projects a red line onto the floor that tells people where to throw darts from.
He mentions in his How-To instructions that his children are older now and the laser is mounted so it doesn't shine in anyone's eyes. But if you want something a little more temporary for your next party, try our idea:
We've already got this Black and Decker laser level in our tool box at home. So the next time we need a regulation throw line for a game of darts or our too-short beer pong table, we'll just plop it down onto the floor (out of the way, along a wall) to project a laser throw line without tape or paint.
