Gents, I finally secured a date with a HB7 in three days time. We met online and she wrote this:

"You sound like a really nice guy but we will only know if there is the necessary spark to take it any further if we meet in person. I'm not into messing people about and I am looking forward to meeting you."

We are going for strawberries and ice-cream. I am looking for ideas on how generate "sparks". This can be in form of text message to confirm meeting or something I should say/asked/do during or meeting.

Another thing, she doesn't know that I wear hearing aids. Should I mention this before the meeting?

Advice will be very much appreciated. Thanks

I would bring a sparkler or two and light it up.

Cheesy but hey it will ease the pressure as already she has put pressure on the situation by indicating there has got to be a spark etc.

It may seem AFC but fuck it.

It's important to keep your cool and don't take everything she said too serious. I get those all the time, normally I would make a joke out of it.
Just walk her to some park, pick up 2 rocks, and start to hit them against each other. If she asks, tell her you're trying to create sparks !!!
Just be playful. Once I told a girl
-You look like you can't wait to kiss me
-Maybe... if you play your cards right...
- Sweet, I played poker for living.

Cool suggestions guys

Perhaps I should add that she is a Biology teacher. Any sparks reference in biology, anyone?

Yes, well I have a degree in Biology so I can bullshit about it but if you want to play that cards. Do some research on Oxytocin, that is the actual hormone which is released from our brain when ppl experience attraction.
You can always make some joke about it, I would just make her eat some weird stuffs and make fun of her while explaining you're doing this is creating sparks. She will ask why and tell her this food increases oxytocin level in your brains.
