Launched SS carts

Dear reader,

I've seen some knex rollercoasters on YouTube in which a screaming serpent cart appears to be launched by Ripping Rocket boosters. Since I own both, I was wondering how this is done, because simply leading the SS cart through those boosters won't work.
Thanks for reading.

Kind regards,

It has nothing to do with physics, like that guy said. You'll have to modify your boosters by cutting some parts of the orange housing off, like Burrito said in the comments here

Here's a quick video on it.

I don't have any SS style roller coasters myself, so I'm afraid I can't help any further, but I hope this information can be of use to you~

everything has to do with Physics!

It applies to this coaster:

again, send me pictures of both elements, I study physics at my highschool right now so i can help you, but i need pictures.
