<human>: Can you succinctly summarize the text in 1-3 sentences?

Alright, I'm relatively new to snapchat (barely 4000 snapscore) and even more new to snapchatting someone I'm interested in dating.  The girl I'm interested in is in no way, shape, or form, new to snapchat (she has nearly 55,000 snapscore).

So, I have snapped her on only one occasion since i added her a week ago (she added me back with the hour).  I waited a day to snap her first, we then had a small snap convo the consisted of like 4 snaps each, she responded every time.  Other than that though, we have not interacted at all on snapchat, I want that to change.  

I think it'd be sweet if we could get a streak going or if I could at least get her to start initiating conversations with ME on there.  So my questions are...  How do you go about snapping someone you're interested in, in our case we are friends irl who talk nearly every day?  What are some ideas that I could use to initialize a conversation with her?  What are you're do's and dont's of snapping a crush?

And before anyone tells me that what I need to be doing is talking to her in person, don't worry, we talk literally every weekday.  I'm just looking for ways to kinda work slowly towards having a more flirtatious vibe with her.  My logic is that snapchats are 1 on 1 interactions, something we have yet to have together considering we're always surrounded by friends at school.
<bot>: Guy wants to snapchat his crush?  How does he do that?  Would it be weird to try and start a snap streak if you've pretty much never snapped each other before?
