Members of #teamgo have begun making fake hands as part of Friday's big reveal.

We don't know exactly what they're planning with them but we do know they want to help people understand the impact of sexual harassment on public transport.

Award winning actor Farhan Akhtar, who is also a UN Women goodwill ambassador, spoke to the BBC about the importance of creating equality at home among the family as a way of helping children form healthy views of women.

Hollaback London, who are advising #teamgo, run workshops for bystanders on what to do if you see harassment happening in front of you.

As #teamgo work on their own ideas for improving public transport for women, we look at the effect of special pink buses designed for women in Turkey. What do you think? Follow their progress on Instagram: http://bit.ly/2hNHABl , externaland tweet @BBC100women, external

Katie Finnegan from Hollaback London, a global network which aims to end street harassment, takes a break from helping our team of experts.

What are they up to?

Classes in Nairobi aim to teach boys and young men what it feels like to be harassed on public transport and how to intervene if they spot it happening.

Some politicians - including Labour Party leader Jeremy Corbyn - have proposed separate carriages for women could be the solution to harassment on public transport.

They have been trialled in many countries, from Mexico to Japan to India, in various forms on buses, trains and taxis. But is there any evidence they make women's lives safer?

Pakistan is a country of stark contrasts, and when it comes to the treatment of women, they are even clearer, writes the BBC's Shumaila Jaffery.

We have finished our live debate for our #teamgo launch on the BBC World Service's Outside Source programme.

But we will have more stories of harassment around the world, and updates to their progress throughout the week, here and on our 100 Women Facebook, external and Twitter, external.

Continue the debate using the hashtag #100Women this week, and listen on Friday to find out what solutions our #teamgo panelists have come up with.

Charlotte Macken says it is great that #teamgo have a bus "to tinker with" this week, because she herself experienced harassment on a bus. Exhausted from writing her dissertation all night, she fell asleep and woke up to find a man touching her.

She said something more may have happened, had the bus driver not stopped the bus and told the perpetrator to stop over the loudspeaker.

She says she's intrigued to find out what the team come up with during the week.

Hanne Bingle from #teamgo, who used to be a TfL tube driver, said she was unprepared to deal with any complaints of harassment.

Val Shawcross, London's deputy mayor for transport, says harassment is taken "extremely seriously" by her department, as the public transport network is crucial to jobs, work and entertainment.

"We have to fight every day to make this safe," she says, adding that there are 12,000 cameras across the London tube network

"We will make sure we will track those people... we do believe you... unwanted touching is criminal."

She makes a commitment to take ideas from #teamgo efforts.

"Good ideas that come forward, we want to take it them forward," she says.

Members of our audience point out that in some packed conditions of the tube, it can be physically difficult to raise the alarm if someone is touching you inappropriately.

Would using an emergency stop button be a solution to this? It's one for #teamgo to ponder when thinking of their solutions this week.

Also in the audience are Kaitlyn Regehr, who experienced harassment on the London Underground, and Firat Ozcelik, who intervened.

Firat told the harasser: "This person could be your sister, she could be your mother" and therefore humanised the event, Kaitlyn explains.

She says that when she shared the experience on social media, there were very gendered reactions.

"Men thought it was a really sad story that I was harassed and women thought it was a really beautiful story that I was helped."

Since Sunday people have been tweeting #MeToo to share their experiences of sexual harassment and abuse, amid allegations against Hollywood producer Harvey Weinstein.

A number of high-profile figures have joined in - the hundreds of thousands of mentions show the scale of the issue for women around the world.
