The beat of this is based on "The Cup Game", a song accompanying an old children's game. Lulu and the Lampshades made it, Pitch Perfect made it popular and Anna Kendrick made it even more popular. Here you will find the steps to learn the song.
Steps

Step 1. Get a hard plastic cup that is not too heavy
If you don't have one, you can also use a bottle. You can also use a disposable paper or plastic cup, but the weight of a slightly heavier cup will keep it from flying out of your hands as you perform the song.

Step 2. Place the cup upside down on a table or other hard surface
Place the cup directly in front of you.
Method 1 of 2: Method one: Right-handed

Step 1. Clap twice

Step 2. Hit the top of the cup three times:
first with your right hand, then with your left hand, and then again with your right hand. You can also hit the table.

Step 3. Clap once

Step 4. Pick up the cup with your right hand so that it is about 5 cm above the table

Step 5. Move the cup about 6 inches to the right and set it down

Tips
- If you do this on a hard surface you will get a better result.
- Hum the beat of the song. That helps you keep the rhythm.
- Once you've become familiar with the moves, you can try singing along with them. "You're Gonna Miss Me" is one of the most popular songs, but many others fit it too. Search YouTube for the Cup song to better understand the instructions.
- Learn the lyrics of the song if you want a challenge!
- Don't hit the cup too hard if you're using a Styrofoam cup.
- Go a little faster with each round of the song. That can be quite a challenge, but keep trying.
- If you want a challenge, meet up with some friends and make it a competition. The rule is: everyone has to make 3 changes to the song. Have a few other friends judge. Good luck!
- Write the song down on paper so you have a copy if you forget it.
- Grab a cup and a sheet of paper and write down both the movements and the lyrics.
- If you don't have a cup handy at school, you can clap your hands or practice on the backs of your friends. If you have time for yourself during class, you can practice with a glue stick or an eraser.
- Larger cups are easier to pick up and move. Keep this in mind when looking for a suitable cup.
- Practice until the song has worn down and you can pick up the beat anywhere.
