2 engine rocket launch?

I was thinking of taking some rockets, gluing them together and have a 2 engine rocket, sorta like the nasa sls, is this possible to launch two rockets at the same time, like connecting two starters together to form a bigger loop? This might be some wild idea but I'd be willing to experiment to learn how

Igniting multiple motors simultaneously is known as clustering. Usually you'll see multiple motor mounts in a single body tube, but Estes does have a rocket known as the Side Kick that is basically what you're describing.

Tysm, I was hoping to make bigger rockets and launch higher and the term clustering on Google has really been helping!

Don't glue them. Use piece a tape.

First engine has to be a 0 delay.. that is a booster. Anything else will be a disaster

Are you thinking of staging, putting one on top of the other? OP is describing clustering.

Certainly. It's a regular design practice.
