How do you woohoo in the future it says on the challenges that you can..

You have to invent a time machine then it will ask you go to the future go to the past woohoo in the future woohoo in the past and try for baby in the future and try for baby in the past

Have two Sims young adult and up (preferably in a romantic relationship) available. Invent a time machine by completing a challenge in the mystery joarnal "the Case of the Curios Painting"- or something like that. Once youv'e made the time machine select a select the time machine then select woohoo in the past, then select another sim to woohoo with. You'll have to have a sim with I think level two inventing skill.

Good luck.

You have to have a skilled inventor sim and they have to build a time machine ( to speed up inventing you should get the " fast learner" and " inventor" lifetime wishes... They usually make it when they r on level eight). After that go to build/buy mode. Click on your inventory and place the time machine. Once back to live mode click on the time machine and click woohoo... And it will give you options: past or future. Click one and choose a sim to do it with. (Make sure they are in a good mood or they will reject the offer to woohoo. And this will NOT make your sim pregnant. Woohooing is just like having sex with a condom on.) You have to wait a couple sim hours/days to go again. Next time do the same exact thing but click on the other option: past or future.

P.S. Sorry for me using the word sex. Please don't report my message. (I just couldn't find another way to say what woohooing meant). I hope I helped. <3 Yall.

First go to build and buy go to entertainment then go to hobbies and skills get the most expensive item which is a workbench you need a good inventor [im not sure what level]when your sim finally finds out how to make the time machine go to make complex invansion then click time machine when you're sim makes the time machine click on it it will say somewhere woohoo in the past woohoo in the future you will then need two sims in a a romantic realationship [mabye when their boyfriend and girlfriend]and their you go thats how.

You keep inventing until you build a time machine, then you get a significant other, invite then to your house, and it should give you the option to do the challenge.
