In one sentence, describe what the following article is about: For this trick, you'll need a piece of cloth or other fabric, two coins, and a table to perform the trick on. Place one of the coins on the table. Lay the cloth on top of the coin so that the coin is under the center of the cloth. The edge of the cloth needs to be flush with the edge of the table. For this trick to work, you'll need to either have something under the table that will muffle the sound of a coin falling, like soft carpet, or a rug, or you'll need to be standing so that the hand not doing the trick can discreetly catch the coin. Now is the time to gather your audience. Ask the audience for a coin to borrow for the trick. If no one has one, use the other coin you brought. Put the coin down on the center of the cloth. Try to place it close to where the other coin beneath the cloth is, but don't worry if it's not exact. Start making a rubbing motion with your hand over the coin, so that your hand is making circles just above it. With each circular motion, touch the coin very gently so that your hand pulls it towards the edge of the table a few inches. Continue doing this until the coin falls of the edge.  If your table isn't over something that will muffle the sound of the coin falling, catch the coin with your other hand. You may need to practice this so that you can do it discreetly. While you're pulling the coin off the table with each circular motion, do some misdirection with your other hand and voice to keep the audience from looking too closely at the place the coin originally was. Remove your hand from above the cloth to show how the coin has disappeared. Then pull the cloth off with your other hand to show the coin beneath the cloth. If you caught the coin as it fell with the other hand, do this quickly so that you can pull the cloth off with the coin still hidden in your hand.
Summary: Gather your materials. Prepare the trick. Start the performance. Place the coin on the cloth. Pull the coin off the cloth. Reveal the other coin.

In one sentence, describe what the following article is about: This is most common dangerous and powerful drugs like heroin. Downers, like opiates, usually leave people in a happy stupor, unable and unwilling to move off the couch they're on. They often squirm around sensually like a baby in blankets, getting comfortable and enjoying every single second of it. Watch Ewan McGregor's masterful performance as a heroin addict in Trainspotting to see how quick this shift can be. Opiates often hit hard, bringing a wave of euphoria, before putting the user into a mellow, sleepy, and often useless state. Most opiate users have their heads blissfully in the clouds. They may start a thought, but finishing it isn't really important. Ask someone's attention, but don't have anything to say when they turn to you. Keep your voice low and quiet. The overall idea is to remain stuck in the clouds, unable to pin down your thoughts. More often than not, this leads to literally falling asleep, your head lolling up in surprise slightly every so often, as if just waking up. Again, this is particularly true of heroin, but drugs like Oxycontin are actually the same type of compound, just slightly weaker. Scratch on your forearms, but don't make a big deal of it. This is just another uncontrollable tic, not some dedicated urge.
Summary:
Act like a sleepy, happy baby, talking little and smiling sleepily. Lurch into wide-eyed happiness right after "taking" the drug, then fade into sleepiness. Let your words and actions drift off into nothing. Drift off regularly, either by falling asleep or simply zoning out into oblivion. Scratch at yourself regularly, as itchiness is often a side-effect of opiates.
